    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value       any JavaScript value, usually an object or array.

            replacer    an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space       an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the value

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear()   + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate())      + 'T' +
                         f(this.getUTCHours())     + ':' +
                         f(this.getUTCMinutes())   + ':' +
                         f(this.getUTCSeconds())   + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if (typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
                    if (a) {
                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
                            +a[5], +a[6]));
                    }
                }
                return value;
            });

            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
                var d;
                if (typeof value === 'string' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {
                    d = new Date(value.slice(5, -1));
                    if (d) {
                        return d;
                    }
                }

                For the particular case of a boundary within a text node containing line breaks (within a <pre> element,
                for example), we need a slightly complicated approach to get the boundary's offset in IE. The facts:

                - Each line break is represented as \r in the text node's data/nodeValue properties
                - Each line break is represented as \r\n in the TextRange's 'text' property
                - The 'text' property of the TextRange does not contain trailing line breaks

                To get round the problem presented by the final fact above, we can use the fact that TextRange's
                moveStart() and moveEnd() methods return the actual number of characters moved, which is not necessarily
                the same as the number of characters it was instructed to move. The simplest approach is to use this to
                store the characters moved when moving both the start and end of the range to the start of the document
                body and subtracting the start offset from the end offset (the "move-negative-gazillion" method).
                However, this is extremely slow when the document is large and the range is near the end of it. Clearly
                doing the mirror image (i.e. moving the range boundaries to the end of the document) has the same
                problem.

                Another approach that works is to use moveStart() to move the start boundary of the range up to the end
                boundary one character at a time and incrementing a counter with the value returned by the moveStart()
                call. However, the check for whether the start boundary has reached the end boundary is expensive, so
                this method is slow (although unlike "move-negative-gazillion" is largely unaffected by the location of
                the range within the document).

                The method below is a hybrid of the two methods above. It uses the fact that a string containing the
                TextRange's 'text' property with each \r\n converted to a single \r character cannot be longer than the
                text of the TextRange, so the start of the range is moved that length initially and then a character at
                a time to make up for any trailing line breaks not contained in the 'text' property. This has good
                performance in most situations compared to the previous two methods.

/**
 * Tree walking functions.
 *
 * prewalk(form, fn, inplace)
 *
 *     Descend into the given form, which is a tree of arrays andmaps
 *     (javascript Object), and build a new tree with the result of
 *     applying the given fn to each branch and leaf. Only arrays and
 *     maps are descended into, everything else is considered a leaf.
 *
 *     The given fn is applied as the tree is descended into - the
 *     function application (pre)cedes descending into the tree.
 * 
 *     By default, an entirely new structure is returned. If the
 *     optional inplace argument is true, the algorithm will not
 *     allocate any new structures, but modify the given form in-place.
 *     The benefit of this is more performance due to less allocation,
 *     and reduced memory overhead, but see the "Note" below.
 *
 * postwalk(form, fn, inplace)
 *
 *     the same as prewalk, except the given fn is applied as the tree
 *     is ascended.
 *
 * preprune(form, pred, inplace)
 *
 *     the same as prewalk, except pred is a predicate function and any
 *     branch or leaf that is encountered and for which pred returns
 *     true is removed from the tree.
 *
 * postprune(form, pred, inplace)
 *
 *     the same as preprune, except the predicate function is applied as
 *     the tree is ascended.
 *
 *     Postpruning is potentially slower than prepruning since it always
 *     descendes into the whole tree, even into pruned nodes, while
 *     prepruning skips any pruned nodes.
 *
 * leaves(form, leaf, inplace)
 *
 *     Like postwalk, except the leaf function is applied only to
 *     leaves, and not to the arrays or maps that make up the tree
 *     structure of form.
 *
 *     Useful when one is only interested in tranforming leaves.
 *
 * flatten(form)
 *
 *     Makes an array of all of the given form's leaves.
 *
 * clone(form)
 *
 *     Constructs a deep clone of the given form.
 *
 * prepruneDom(form, pred, inplace)
 *
 *     Like preprune() except:
 *
 *     - the given form may be either an element or other DOM node, and
 *       only elements are descended into, all other node types are
 *       considered leaves.
 *
 *     - the given form will be cloned before it is being traversed, unless
 *       inplace is true.
 *
 *       This is different from prewalk, where the subforms that are
 *       passed to fn are not clones. Making a deep clone first
 *       simplifies some things, basically because an array or map can
 *       be the child of multiple arrays and maps at the same time,
 *       while a node can only be the child of a single parent node at
 *       any one time.
 *   
 * postpruneDom(form, pred, inplace)
 *
 *     Like prepruneDom(), except the given function is applied as the tree
 *     is ascended.
 *
 * walk(form, recurse, inplace)
 *
 *     If form is an array or map, calls recurse on each of its items.
 *     If inplace is true, modifies the form and sets each item to the
 *     result of the call to recurse. If inplace is false, creates a new
 *     array/map containing the results of calling recurse. Returns
 *     either form if inplace is true, or the newly created array/map.
 *
 *     If form is not an array or map, it is simply returned.
 *
 *     An example using walk() in a custom recursive traversal function:
 * 
 *     function doSomething(root) {
 *         function step(form) {
 *             form = Trees.walk(form, step);
 *             // do something with form
 *             return form ? [form] : [];
 *         }
 *         return step(root)[0] || null;
 *     }
 *
 * walk(form, recurse)
 *
 *     Short for walk(form, recurse, true)
 *
 * walkDomInplace(form, recurse)
 *
 *     Similar to walk() but operates on DOM nodes.
 *
 *     Elements are considered non-leaf, and everything else is
 *     considerd a leaf.
 *
 * Note: All functions work on array+map trees, unless they are suffixed
 *       with Dom, in which case they only work on DOM nodes.
 *
 * Note: When walking arrays and maps, if the fn and leaf functions
 *       modify the parent or any ancestor of the passed form, the
 *       resulting behaviour is undefined. Only modification of the
 *       passed form and descendants of the passed form is valid.
 *
 *       During DOM traversal, it is allowed to insert-into/remove-from
 *       the children of the parent of the given form, as long the given
 *       form itself is not removed.
 *
 * Note: the algorithms are recursive and the maximum nesting level of
 *       the input set is therefore bound to the maximum stack depth.
 *       IE7 and IE8 for example have a maximum stack depth of greater
 *       than 1000, so the maximum input nesting level should not exceed
 *       about 300 (3 stack frames are needed per nesting level).

/**
 * Provides functions to mark the contents of editables as ephemeral. An
 * editable's ephemeral content will be pruned before it is being
 * returned by editable.getContents().
 * 
 * It is planned to replace most instances of makeClean() with this
 * implementation for improved performance and more importantly, in
 * order to have a centralized place that has the control over all
 * ephemeral content, which can be leveraged by plugins to provide more
 * advanced functionality.
 *
 * Some examples that would be possible:
 * * a HTML source code text box, an interactive tree structure, or
 *   other kind of DOM visualization, next to the editable, that
 *   contains just the content of the editable (without ephemeral data)
 *   and which is updated efficiently in real time after each keystroke.
 *
 * * change detection algorithms that are able to intelligently ignore
 *   ephemeral data and which would not trigger unless non-ephemeral
 *   data is added to the editable.
 *
 * * When a plugin provides very general functionality over all nodes of
 *   the DOM, somtimes the plugin may not know what is and what isn't
 *   supposed to be real content. The functionality provided here makes
 *   it possible for the plugin to exaclty distinguish real content from
 *   ephemeral content.
 *
 * TODO: currently only simple transformations are suppored, like
 *       marking classes, attributes and elements as ephemeral and removing
 *       them during the pruning process.
 *       In the future, support for the block-plugin and custom pruning
 *       functions should be added. This may be done by letting implementations
 *       completely control the pruning of a DOM element through a
 *       function that takes the content+ephemeral-data and returns only
 *       content - similar to make clean, but for single elements to reduce
 *       overhead.

	//			Action: What the command does when executed via execCommand(). Every command defined
	//			in CommandManager specification has an action defined for it in the relevant section. For example,
	//			the bold command's action generally makes the current selection bold, or removes bold if
	//			the selection is already bold. An editing toolbar might provide buttons that execute the
	//			action for a command if clicked, or a script might run an action without user interaction
	//			to achieve some particular effect.
	//
	//			Indeterminate: A boolean value returned by queryCommandIndeterm(), depending on the
	//			current state of the document. Generally, a command that has a state defined will be
	//			indeterminate if the state is true for part but not all of the current selection, and a
	//			command that has a value defined will be indeterminate if different parts of the
	//			selection have different values. An editing toolbar might display a button or control
	//			in a special way if the command is indeterminate, like showing a "bold" button as
	//			partially depressed, or leaving a font size selector blank instead of showing the font
	//			size of the current selection. As a rule, a command can only be indeterminate if its
	//			state is false, supposing it has a state.
	//
	//			State: A boolean value returned by queryCommandState(), depending on the current state
	//			of the document. The state of a command is true if it is already in effect, in some
	//			sense specific to the command. Most commands that have a state defined will take opposite
	//			actions depending on whether the state is true or false, such as making the selection
	//			bold if the state is false and removing bold if the state is true. Others will just
	//			have no effect if the state is true, like the justifyCenter command. Still others will
	//			have the same effect regardless, like the styleWithCss command. An editing toolbar might
	//			display a button or control differently depending on the state and indeterminacy of the
	//			command.
	//
	//			Value: A string returned by queryCommandValue(), depending on the current state of the
	//			document. A command usually has a value instead of a state if the property it modifies
	//			can take more than two different values, like the foreColor command. If the command is
	//			indeterminate, its value is generally based on the start of the selection. Otherwise,
	//			in most cases the value holds true for the entire selection, but see the justifyCenter
	//			command and its three companions for an exception. An editing toolbar might display the
	//			value of a command as selected in a drop-down or filled in in a text box, if the command
	//			isn't indeterminate.
	//
	//			Relevant CSS property: CommandManager is defined for certain inline formatting commands, and
	//			is used in algorithms specific to those commands. It is an implementation detail, and
	//			is not exposed to authors. If a command does not have a relevant CSS property
	//			specified, it defaults to null.

 * This plugin handles i18n! prefixed modules. It does the following:
 *
 * 1) A regular module can have a dependency on an i18n bundle, but the regular
 * module does not want to specify what locale to load. So it just specifies
 * the top-level bundle, like "i18n!nls/colors".
 *
 * This plugin will load the i18n bundle at nls/colors, see that it is a root/master
 * bundle since it does not have a locale in its name. It will then try to find
 * the best match locale available in that master bundle, then request all the
 * locale pieces for that best match locale. For instance, if the locale is "en-us",
 * then the plugin will ask for the "en-us", "en" and "root" bundles to be loaded
 * (but only if they are specified on the master bundle).
 *
 * Once all the bundles for the locale pieces load, then it mixes in all those
 * locale pieces into each other, then finally sets the context.defined value
 * for the nls/colors bundle to be that mixed in locale.
 *
 * 2) A regular module specifies a specific locale to load. For instance,
 * i18n!nls/fr-fr/colors. In this case, the plugin needs to load the master bundle
 * first, at nls/colors, then figure out what the best match locale is for fr-fr,
 * since maybe only fr or just root is defined for that locale. Once that best
 * fit is found, all of its locale pieces need to have their bundles loaded.
 *
 * Once all the bundles for the locale pieces load, then it mixes in all those
 * locale pieces into each other, then finally sets the context.defined value
 * for the nls/fr-fr/colors bundle to be that mixed in locale.

/**
 * Aloha Editor User Interface API Semantics
 * =========================================
 *
 * Note
 * ===
 *    * This documentation is "thinking out loud," and very much "work in work
 *      in progress--as is the Aloha UI API itself.
 *
 *    * For flexibility and ease, it seems that it would be best that the Aloha
 *      UI API will not constrain the developer to these semantics, but will
 *      naively assume that these semantics are observed.
 *
 * Components (Buttons, Labels, Icons)
 * ---
 * Aloha Editor represents its user interface using objects called
 * `components`.  A uniform interface for these components allows them to be
 * agnostic to what container they are rendered on.
 *
 * Controls (Buttons)
 * ---
 * Interactive components like buttons, are called `controls`, to distinguish
 * them from non-interactive components like labels, and icons.
 *
 * Containers (Tabs, Panels)
 * ---
 * In rendering the UI, components are organized in visual groups, and these
 * groups are in turn bundled onto `containers`.  Containers can be tabs, as in
 * the case of the floating menu, or panels like in the sidebar.  Containers
 * allow a collection of controls that represent a feature set to be rendered
 * as a group and to be brought in and out of view together.
 *
 * Surfaces (Toolbar, Sidebar, Ribbon)
 * ---
 * `Surfaces` are areas on a web page in which containers can be placed.  The
 * sidebar, and the toolbar are examples of such surfaces.  The possibility
 * exists for other surfaces to be defined--such as a ribbon, or a footer menu.
 *
 *
 * Class structure

 * Enforcing good dependencies
 * ===
 * In order to void subtle errors that arise from erroneous dependency
 * declarations, we will have ill-defined or missing dependencies fail early
 * and noisily.  We achieve this by never exposing individual modules through
 * the Aloha.ui hash unless absolutely necessary. Modules are accessibly only
 * through require.
 *
 * How this works:
 * For example, a ui module "uiModule" would not be exposed through
 * `Aloha.ui.uiModule` but from require's `define` call:
 *
 *		define([ 'ui/uiModule' ], function( uiModule ) {});
 *
 * or
 *
 *		var uiModule = Aloha.require( 'ui/uiModule' );
 * 
 * This will force more deliberate and precise usage of dependencies.  The
 * developer will have to know exactly which direct dependencies they are using;
 * any missing or unsuccessfully require dependency will not inadvertantly be
 * provided from another require somewhere else in Aloha thereby silencing an
 * error that will emerge unexpectedly if that require is ever removed.

		 * implemented in IE for example). Some effort was made to fix a
		 * broken DOM structure, if it is encountered. There is one case
		 * which results in an unrecoverably broken DOM structure, which
		 * is an unrecognized element not preceded by some text. See the
		 * tests for further information.
		 *
		 * IE8 bug: whitespace is not reliably preserved when the style
		 * white-space:pre (or similar) is used. See the tests for
		 * further information. Whitespace inside <pre> elements will
		 * be preserved, but \n characters will become \r characters.
		 *
		 * IE7 bug: URLs in href and src attributes of a and img
		 * elements will be absolutized (including hostname and
		 * protocol) if they are given as a relative path.
		 *
		 * IE bug: Namespace support inside contentEditable=true is a
		 * bit shaky on IE. Don't use it if possible. See the tests to
		 * get an idea of what seems to work. Make namespace prefixes
		 * and element names all lower-case, as they are always
