			 * Type based search formatting.
			 *
			 * The type based searching functions can be used to pre-format the
			 * data to be search on. For example, it can be used to strip HTML
			 * tags or to de-format telephone numbers for numeric only searching.
			 *
			 * Note that is a search is not defined for a column of a given type,
			 * no search formatting will be performed.
			 * 
			 * Pre-processing of searching data plug-ins - When you assign the sType
			 * for a column (or have it automatically detected for you by DataTables
			 * or a type detection plug-in), you will typically be using this for
			 * custom sorting, but it can also be used to provide custom searching
			 * by allowing you to pre-processing the data and returning the data in
			 * the format that should be searched upon. This is done by adding
			 * functions this object with a parameter name which matches the sType
			 * for that target column. This is the corollary of <i>afnSortData</i>
			 * for searching data.
			 *
			 * The functions defined take a single parameter:
			 *
		     *  1. `{*}` Data from the column cell to be prepared for searching
			 *
			 * Each function is expected to return:
			 *
			 * * `{string|null}` Formatted string that will be used for the searching.
			 *
			 *  @type object
			 *  @default {}
			 *
			 *  @example
			 *    $.fn.dataTable.ext.type.search['title-numeric'] = function ( d ) {
			 *      return d.replace(/\n/g," ").replace( /<.*?>/g, "" );

			/**
			 * Type based ordering.
			 *
			 * The column type tells DataTables what ordering to apply to the table
			 * when a column is sorted upon. The order for each type that is defined,
			 * is defined by the functions available in this object.
			 *
			 * Each ordering option can be described by three properties added to
			 * this object:
			 *
			 * * `{type}-pre` - Pre-formatting function
			 * * `{type}-asc` - Ascending order function
			 * * `{type}-desc` - Descending order function
			 *
			 * All three can be used together, only `{type}-pre` or only
			 * `{type}-asc` and `{type}-desc` together. It is generally recommended
			 * that only `{type}-pre` is used, as this provides the optimal
			 * implementation in terms of speed, although the others are provided
			 * for compatibility with existing Javascript sort functions.
			 *
			 * `{type}-pre`: Functions defined take a single parameter:
			 *
		     *  1. `{*}` Data from the column cell to be prepared for ordering
			 *
			 * And return:
			 *
			 * * `{*}` Data to be sorted upon
			 *
			 * `{type}-asc` and `{type}-desc`: Functions are typical Javascript sort
			 * functions, taking two parameters:
			 *
		     *  1. `{*}` Data to compare to the second parameter
		     *  2. `{*}` Data to compare to the first parameter
			 *
			 * And returning:
			 *
			 * * `{*}` Ordering match: <0 if first parameter should be sorted lower
			 *   than the second parameter, ===0 if the two parameters are equal and
			 *   >0 if the first parameter should be sorted height than the second
			 *   parameter.
			 * 
			 *  @type object
			 *  @default {}
			 *
			 *  @example
			 *    // Numeric ordering of formatted numbers with a pre-formatter
			 *    $.extend( $.fn.dataTable.ext.type.order, {
			 *      "string-pre": function(x) {
			 *        a = (a === "-" || a === "") ? 0 : a.replace( /[^\d\-\.]/g, "" );
			 *        return parseFloat( a );
			 *      }
			 *    } );
			 *
			 *  @example
			 *    // Case-sensitive string ordering, with no pre-formatting method
			 *    $.extend( $.fn.dataTable.ext.order, {
			 *      "string-case-asc": function(x,y) {
			 *        return ((x < y) ? -1 : ((x > y) ? 1 : 0));
			 *      },
			 *      "string-case-desc": function(x,y) {

	/**
	 * DataTables API class - used to control and interface with  one or more
	 * DataTables enhanced tables.
	 *
	 * The API class is heavily based on jQuery, presenting a chainable interface
	 * that you can use to interact with tables. Each instance of the API class has
	 * a "context" - i.e. the tables that it will operate on. This could be a single
	 * table, all tables on a page or a sub-set thereof.
	 *
	 * Additionally the API is designed to allow you to easily work with the data in
	 * the tables, retrieving and manipulating it as required. This is done by
	 * presenting the API class as an array like interface. The contents of the
	 * array depend upon the actions requested by each method (for example
	 * `rows().nodes()` will return an array of nodes, while `rows().data()` will
	 * return an array of objects or arrays depending upon your table's
	 * configuration). The API object has a number of array like methods (`push`,
	 * `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
	 * `unique` etc) to assist your working with the data held in a table.
	 *
	 * Most methods (those which return an Api instance) are chainable, which means
	 * the return from a method call also has all of the methods available that the
	 * top level object had. For example, these two calls are equivalent:
	 *
	 *     // Not chained
	 *     api.row.add( {...} );
	 *     api.draw();
	 *
	 *     // Chained
	 *     api.row.add( {...} ).draw();
	 *
	 * @class DataTable.Api
	 * @param {array|object|string|jQuery} context DataTable identifier. This is
	 *   used to define which DataTables enhanced tables this API will operate on.
	 *   Can be one of:
	 *
	 *   * `string` - jQuery selector. Any DataTables' matching the given selector
	 *     with be found and used.
	 *   * `node` - `TABLE` node which has already been formed into a DataTable.
	 *   * `jQuery` - A jQuery object of `TABLE` nodes.
	 *   * `object` - DataTables settings object
	 * @param {array} [data] Data to initialise the Api instance with.
	 *
	 * @example
	 *   // Direct initialisation during DataTables construction
	 *   var api = $('#example').DataTable();
	 *
	 * @example
	 *   // Initialisation using a DataTables jQuery object
	 *   var api = $('#example').dataTable().api();
	 *
	 * @example
	 *   // Initialisation as a constructor
	 *   var api = new DataTable.Api( 'table.dataTable' );

		 * DataTables can be instructed to load data to display in the table from a

		 *
		 * * `string` - Set the URL from where the data should be loaded from.
		 * * `object` - Define properties for `jQuery.ajax`.
		 * * `function` - Custom data get function
		 *
		 * `string`
		 * --------
		 *
		 * As a string, the `ajax` property simply defines the URL from which
		 * DataTables will load data.
		 *
		 * `object`
		 * --------
		 *
		 * As an object, the parameters in the object are passed to
		 * [jQuery.ajax](https://api.jquery.com/jQuery.ajax/) allowing fine control
		 * of the Ajax request. DataTables has a number of default parameters which
		 * you can override using this option. Please refer to the jQuery
		 * documentation for a full description of the options available, although
		 * the following parameters provide additional options in DataTables or
		 * require special consideration:
		 *
		 * * `data` - As with jQuery, `data` can be provided as an object, but it
		 *   can also be used as a function to manipulate the data DataTables sends
		 *   to the server. The function takes a single parameter, an object of
		 *   parameters with the values that DataTables has readied for sending. An
		 *   object may be returned which will be merged into the DataTables
		 *   defaults, or you can add the items to the object that was passed in and
		 *   not return anything from the function. This supersedes `fnServerParams`
		 *   from DataTables 1.9-.
		 *
		 * * `dataSrc` - By default DataTables will look for the property `data` (or
		 *   `aaData` for compatibility with DataTables 1.9-) when obtaining data
		 *   from an Ajax source or for server-side processing - this parameter
		 *   allows that property to be changed. You can use Javascript dotted
		 *   object notation to get a data source for multiple levels of nesting, or
		 *   it my be used as a function. As a function it takes a single parameter,
		 *   the JSON returned from the server, which can be manipulated as
		 *   required, with the returned value being that used by DataTables as the
		 *   data source for the table.
		 *
		 * * `success` - Should not be overridden it is used internally in
		 *   DataTables. To manipulate / transform the data returned by the server
		 *   use `ajax.dataSrc`, or use `ajax` as a function (see below).
		 *
		 * `function`
		 * ----------
		 *
		 * As a function, making the Ajax call is left up to yourself allowing
		 * complete control of the Ajax request. Indeed, if desired, a method other
		 * than Ajax could be used to obtain the required data, such as Web storage
		 * or an AIR database.
		 *
		 * The function is given four parameters and no return is required. The
		 * parameters are:
		 *
		 * 1. _object_ - Data to send to the server
		 * 2. _function_ - Callback function that must be executed when the required
		 *    data has been obtained. That data should be passed into the callback
		 *    as the only parameter

		 *   DataTables reads the data from the source object:
		 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
		 *      Javascript to read from nested objects, so to can the options
		 *      specified in `data`. For example: `browser.version` or
		 *      `browser.name`. If your object parameter name contains a period, use
		 *      `\\` to escape it - i.e. `first\\.name`.
		 *    * `[]` - Array notation. DataTables can automatically combine data
		 *      from and array source, joining the data with the characters provided
		 *      between the two brackets. For example: `name[, ]` would provide a
		 *      comma-space separated list from the source array. If no characters
		 *      are provided between the brackets, the original array source is
		 *      returned.
		 *    * `()` - Function notation. Adding `()` to the end of a parameter will
		 *      execute a function of the name given. For example: `browser()` for a
		 *      simple function on the data source, `browser.version()` for a
		 *      function in a nested property or even `browser().version` to get an
		 *      object property if the function called returns an object. Note that
		 *      function notation is recommended for use in `render` rather than
		 *      `data` as it is much simpler to use as a renderer.
		 * * `null` - use the original data source for the row rather than plucking
		 *   data directly from it. This action has effects on two other
		 *   initialisation options:
		 *    * `defaultContent` - When null is given as the `data` option and
		 *      `defaultContent` is specified for the column, the value defined by
		 *      `defaultContent` will be used for the cell.
		 *    * `render` - When null is used for the `data` option and the `render`
		 *      option is specified for the column, the whole data source for the
		 *      row is used for the renderer.
		 * * `function` - the function given will be executed whenever DataTables
		 *   needs to set or get the data for a cell in the column. The function
		 *   takes three parameters:
		 *    * Parameters:
		 *      * `{array|object}` The data source for the row
		 *      * `{string}` The type call data requested - this will be 'set' when
		 *        setting data or 'filter', 'display', 'type', 'sort' or undefined
		 *        when gathering data. Note that when `undefined` is given for the
		 *        type DataTables expects to get the raw data for the object back<
		 *      * `{*}` Data to set when the second parameter is 'set'.

		 *
		 * Note that `data` is a getter and setter option. If you just require

		 *
		 * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The

		/**
		 * This property is the rendering partner to `data` and it is suggested that
		 * when you want to manipulate data for display (including filtering,
		 * sorting etc) without altering the underlying data for the table, use this
		 * property. `render` can be considered to be the the read only companion to
		 * `data` which is read / write (then as such more complex). Like `data`
		 * this option can be given in a number of different ways to effect its
		 * behaviour:
		 *
		 * * `integer` - treated as an array index for the data source. This is the
		 *   default that DataTables uses (incrementally increased for each column).
		 * * `string` - read an object property from the data source. There are
		 *   three 'special' options that can be used in the string to alter how
		 *   DataTables reads the data from the source object:
		 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
		 *      Javascript to read from nested objects, so to can the options
		 *      specified in `data`. For example: `browser.version` or
		 *      `browser.name`. If your object parameter name contains a period, use
		 *      `\\` to escape it - i.e. `first\\.name`.
		 *    * `[]` - Array notation. DataTables can automatically combine data
		 *      from and array source, joining the data with the characters provided
		 *      between the two brackets. For example: `name[, ]` would provide a
		 *      comma-space separated list from the source array. If no characters
		 *      are provided between the brackets, the original array source is
		 *      returned.
		 *    * `()` - Function notation. Adding `()` to the end of a parameter will
		 *      execute a function of the name given. For example: `browser()` for a
		 *      simple function on the data source, `browser.version()` for a
		 *      function in a nested property or even `browser().version` to get an
		 *      object property if the function called returns an object.
		 * * `object` - use different data for the different data types requested by
		 *   DataTables ('filter', 'display', 'type' or 'sort'). The property names
		 *   of the object is the data type the property refers to and the value can
		 *   defined using an integer, string or function using the same rules as
		 *   `render` normally does. Note that an `_` option _must_ be specified.
		 *   This is the default value to use if you haven't specified a value for
		 *   the data type requested by DataTables.
		 * * `function` - the function given will be executed whenever DataTables
		 *   needs to set or get the data for a cell in the column. The function
		 *   takes three parameters:
		 *    * Parameters:
		 *      * {array|object} The data source for the row (based on `data`)
		 *      * {string} The type call data requested - this will be 'filter',
		 *        'display', 'type' or 'sort'.
		 *      * {array|object} The full data source for the row (not based on
		 *        `data`)
		 *    * Return:
		 *      * The return value from the function is what will be used for the
		 *        data requested.

	/**
	 * Helpers for `columns.render`.
	 *
	 * The options defined here can be used with the `columns.render` initialisation
	 * option to provide a display renderer. The following functions are defined:
	 *
	 * * `moment` - Uses the MomentJS library to convert from a given format into another.
	 * This renderer has three overloads:
	 *   * 1 parameter:
	 *     * `string` - Format to convert to (assumes input is ISO8601 and locale is `en`)
	 *   * 2 parameters:
	 *     * `string` - Format to convert from
	 *     * `string` - Format to convert to. Assumes `en` locale
	 *   * 3 parameters:
	 *     * `string` - Format to convert from
	 *     * `string` - Format to convert to
	 *     * `string` - Locale
	 * * `number` - Will format numeric data (defined by `columns.data`) for
	 *   display, retaining the original unformatted data for sorting and filtering.
	 *   It takes 5 parameters:
	 *   * `string` - Thousands grouping separator
	 *   * `string` - Decimal point indicator
	 *   * `integer` - Number of decimal points to show
	 *   * `string` (optional) - Prefix.
	 *   * `string` (optional) - Postfix (/suffix).
	 * * `text` - Escape HTML to help prevent XSS attacks. It has no optional
	 *   parameters.
	 *
	 * @example
	 *   // Column definition using the number renderer
	 *   {
	 *     data: "salary",
	 *     render: $.fn.dataTable.render.number( '\'', '.', 0, '$' )
	 *   }

/**
 * @name MarkerClustererPlus for Google Maps V3
 * @version 2.1.2 [May 28, 2014]
 * @author Gary Little
 * @fileoverview
 * The library creates and manages per-zoom-level clusters for large amounts of markers.
 * <p>
 * This is an enhanced V3 implementation of the
 * <a href="http://gmaps-utility-library-dev.googlecode.com/svn/tags/markerclusterer/"
 * >V2 MarkerClusterer</a> by Xiaoxi Wu. It is based on the
 * <a href="http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/"
 * >V3 MarkerClusterer</a> port by Luke Mahe. MarkerClustererPlus was created by Gary Little.
 * <p>
 * v2.0 release: MarkerClustererPlus v2.0 is backward compatible with MarkerClusterer v1.0. It
 *  adds support for the <code>ignoreHidden</code>, <code>title</code>, <code>batchSizeIE</code>,
 *  and <code>calculator</code> properties as well as support for four more events. It also allows
 *  greater control over the styling of the text that appears on the cluster marker. The
 *  documentation has been significantly improved and the overall code has been simplified and
 *  polished. Very large numbers of markers can now be managed without causing Javascript timeout
 *  errors on Internet Explorer. Note that the name of the <code>clusterclick</code> event has been
 *  deprecated. The new name is <code>click</code>, so please change your application code now.

/**
 * @name ClusterIconStyle
 * @class This class represents the object for values in the <code>styles</code> array passed
 *  to the {@link MarkerClusterer} constructor. The element in this array that is used to
 *  style the cluster icon is determined by calling the <code>calculator</code> function.
 *
 * @property {string} url The URL of the cluster icon image file. Required.
 * @property {number} height The display height (in pixels) of the cluster icon. Required.
 * @property {number} width The display width (in pixels) of the cluster icon. Required.
 * @property {Array} [anchorText] The position (in pixels) from the center of the cluster icon to
 *  where the text label is to be centered and drawn. The format is <code>[yoffset, xoffset]</code>
 *  where <code>yoffset</code> increases as you go down from center and <code>xoffset</code>
 *  increases to the right of center. The default is <code>[0, 0]</code>.
 * @property {Array} [anchorIcon] The anchor position (in pixels) of the cluster icon. This is the
 *  spot on the cluster icon that is to be aligned with the cluster position. The format is
 *  <code>[yoffset, xoffset]</code> where <code>yoffset</code> increases as you go down and
 *  <code>xoffset</code> increases to the right of the top-left corner of the icon. The default
 *  anchor position is the center of the cluster icon.
 * @property {string} [textColor="black"] The color of the label text shown on the
 *  cluster icon.
 * @property {number} [textSize=11] The size (in pixels) of the label text shown on the
 *  cluster icon.
 * @property {string} [textDecoration="none"] The value of the CSS <code>text-decoration</code>
 *  property for the label text shown on the cluster icon.
 * @property {string} [fontWeight="bold"] The value of the CSS <code>font-weight</code>
 *  property for the label text shown on the cluster icon.
 * @property {string} [fontStyle="normal"] The value of the CSS <code>font-style</code>
 *  property for the label text shown on the cluster icon.
 * @property {string} [fontFamily="Arial,sans-serif"] The value of the CSS <code>font-family</code>
 *  property for the label text shown on the cluster icon.
 * @property {string} [backgroundPosition="0 0"] The position of the cluster icon image

/**
 * @name MarkerClustererOptions
 * @class This class represents the optional parameter passed to
 *  the {@link MarkerClusterer} constructor.
 * @property {number} [gridSize=60] The grid size of a cluster in pixels. The grid is a square.
 * @property {number} [maxZoom=null] The maximum zoom level at which clustering is enabled or
 *  <code>null</code> if clustering is to be enabled at all zoom levels.
 * @property {boolean} [zoomOnClick=true] Whether to zoom the map when a cluster marker is
 *  clicked. You may want to set this to <code>false</code> if you have installed a handler
 *  for the <code>click</code> event and it deals with zooming on its own.
 * @property {boolean} [averageCenter=false] Whether the position of a cluster marker should be
 *  the average position of all markers in the cluster. If set to <code>false</code>, the
 *  cluster marker is positioned at the location of the first marker added to the cluster.
 * @property {number} [minimumClusterSize=2] The minimum number of markers needed in a cluster
 *  before the markers are hidden and a cluster marker appears.
 * @property {boolean} [ignoreHidden=false] Whether to ignore hidden markers in clusters. You
 *  may want to set this to <code>true</code> to ensure that hidden markers are not included
 *  in the marker count that appears on a cluster marker (this count is the value of the
 *  <code>text</code> property of the result returned by the default <code>calculator</code>).
 *  If set to <code>true</code> and you change the visibility of a marker being clustered, be
 *  sure to also call <code>MarkerClusterer.repaint()</code>.
 * @property {string} [title=""] The tooltip to display when the mouse moves over a cluster
 *  marker. (Alternatively, you can use a custom <code>calculator</code> function to specify a
 *  different tooltip for each cluster marker.)
 * @property {function} [calculator=MarkerClusterer.CALCULATOR] The function used to determine
 *  the text to be displayed on a cluster marker and the index indicating which style to use
 *  for the cluster marker. The input parameters for the function are (1) the array of markers
 *  represented by a cluster marker and (2) the number of cluster icon styles. It returns a
 *  {@link ClusterIconInfo} object. The default <code>calculator</code> returns a
 *  <code>text</code> property which is the number of markers in the cluster and an
 *  <code>index</code> property which is one higher than the lowest integer such that
 *  <code>10^i</code> exceeds the number of markers in the cluster, or the size of the styles
 *  array, whichever is less. The <code>styles</code> array element used has an index of
 *  <code>index</code> minus 1. For example, the default <code>calculator</code> returns a
 *  <code>text</code> value of <code>"125"</code> and an <code>index</code> of <code>3</code>
 *  for a cluster icon representing 125 markers so the element used in the <code>styles</code>
 *  array is <code>2</code>. A <code>calculator</code> may also return a <code>title</code>
 *  property that contains the text of the tooltip to be used for the cluster marker. If
 *   <code>title</code> is not defined, the tooltip is set to the value of the <code>title</code>
 *   property for the MarkerClusterer.
 * @property {string} [clusterClass="cluster"] The name of the CSS class defining general styles
 *  for the cluster markers. Use this class to define CSS styles that are not set up by the code
 *  that processes the <code>styles</code> array.
 * @property {Array} [styles] An array of {@link ClusterIconStyle} elements defining the styles
 *  of the cluster markers to be used. The element to be used to style a given cluster marker
 *  is determined by the function defined by the <code>calculator</code> property.
 *  The default is an array of {@link ClusterIconStyle} elements whose properties are derived
 *  from the values for <code>imagePath</code>, <code>imageExtension</code>, and
 *  <code>imageSizes</code>.
 * @property {boolean} [enableRetinaIcons=false] Whether to allow the use of cluster icons that
 * have sizes that are some multiple (typically double) of their actual display size. Icons such
 * as these look better when viewed on high-resolution monitors such as Apple's Retina displays.
 * Note: if this property is <code>true</code>, sprites cannot be used as cluster icons.
 * @property {number} [batchSize=MarkerClusterer.BATCH_SIZE] Set this property to the
 *  number of markers to be processed in a single batch when using a browser other than
 *  Internet Explorer (for Internet Explorer, use the batchSizeIE property instead).
 * @property {number} [batchSizeIE=MarkerClusterer.BATCH_SIZE_IE] When Internet Explorer is
 *  being used, markers are processed in several batches with a small delay inserted between
 *  each batch in an attempt to avoid Javascript timeout errors. Set this property to the
 *  number of markers to be processed in a single batch; select as high a number as you can
 *  without causing a timeout error in the browser. This number might need to be as low as 100
 *  if 15,000 markers are being managed, for example.
 * @property {string} [imagePath=MarkerClusterer.IMAGE_PATH]
 *  The full URL of the root name of the group of image files to use for cluster icons.
 *  The complete file name is of the form <code>imagePath</code>n.<code>imageExtension</code>
 *  where n is the image file number (1, 2, etc.).
 * @property {string} [imageExtension=MarkerClusterer.IMAGE_EXTENSION]
 *  The extension name for the cluster icon image files (e.g., <code>"png"</code> or
 *  <code>"jpg"</code>).
 * @property {Array} [imageSizes=MarkerClusterer.IMAGE_SIZES]
 *  An array of numbers containing the widths of the group of
 *  <code>imagePath</code>n.<code>imageExtension</code> image files.
 *  (The images are assumed to be square.)
