/**
 * This is the main class for the Mixpanel PHP Library which provides all of the methods you need to track events,
 * create/update profiles and group profiles.
 *
 * Architecture
 * -------------
 *
 * This library is built such that all messages are buffered in an in-memory "queue"
 * The queue will be automatically flushed at the end of every request. Alternatively, you can call "flush()" manually
 * at any time. Flushed messages will be passed to a Consumer's "persist" method. The library comes with a handful of
 * Consumers. The "CurlConsumer" is used by default which will send the messages to Mixpanel using forked cURL processes.
 * You can implement your own custom Consumer to customize how a message is sent to Mixpanel. This can be useful when
 * you want to put messages onto a distributed queue (such as ActiveMQ or Kestrel) instead of writing to Mixpanel in
 * the user thread.
 *
 * Options
 * -------------
 *
 * <table width="100%" cellpadding="5">
 *  <tr>
 *      <th>Option</th>
 *      <th>Description</th>
 *      <th>Default</th>
 *  </tr>
 *  <tr>
 *      <td>max_queue_size</td>
 *      <td>The maximum number of items to buffer in memory before flushing</td>
 *      <td>1000</td>
 *  </tr>
 *  <tr>
 *      <td>debug</td>
 *      <td>Enable/disable debug mode</td>
 *      <td>false</td>
 *  </tr>
 *  <tr>
 *      <td>consumer</td>
 *      <td>The consumer to use for writing messages</td>
 *      <td>curl</td>
 *  </tr>
 *  <tr>
 *      <td>consumers</td>
 *      <td>An array of custom consumers in the format array(consumer_key => class_name)</td>
 *      <td>null</td>
 *  </tr>
 *  <tr>
 *      <td>host</td>
 *      <td>The host name for api calls (used by some consumers)</td>
 *      <td>api.mixpanel.com</td>
 *  </tr>
 *  <tr>
 *      <td>events_endpoint</td>
 *      <td>The endpoint for tracking events (relative to the host)</td>
 *      <td>/events</td>
 *  </tr>
 *  <tr>
 *      <td>people_endpoint</td>
 *      <td>The endpoint for making people updates (relative to the host)</td>
 *      <td>/engage</td>
 *  </tr>
 *  <tr>
 *      <td>use_ssl</td>
 *      <td>Tell the consumer whether or not to use ssl (when available)</td>
 *      <td>true</td>
 *  </tr>
 *  <tr>
 *      <td>error_callback</td>
 *      <td>The name of a function to be called on consumption failures</td>
 *      <td>null</td>
 *  </tr>
 *  <tr>
 *      <td>connect_timeout</td>
 *      <td>In both the SocketConsumer and CurlConsumer, this is used for the connection timeout (i.e. How long it has take to actually make a connection).
 *      <td>5</td>
 *  </tr>
 *  <tr>
 *      <td>timeout</td>
 *      <td>In the CurlConsumer (non-forked), it is used to determine how long the cURL call has to execute.
 *      <td>30</td>
 *  </tr>
 * </table>
 *
 * Example: Tracking an Event
 * -------------
 *
 * $mp = Mixpanel::getInstance("MY_TOKEN");
 *
 * $mp->track("My Event");
 *
 * Example: Setting Profile Properties
 * -------------
 *
 * $mp = Mixpanel::getInstance("MY_TOKEN", array("use_ssl" => false));
 *
 * $mp->people->set(12345, array(
 * '$first_name'       => "John",
 * '$last_name'        => "Doe",
 * '$email'            => "john.doe@example.com",
 * '$phone'            => "5555555555",
 * 'Favorite Color'    => "red"
 * ));
