* 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.
* 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
* <table width="100%" cellpadding="5">
* <td>max_queue_size</td>
* <td>The maximum number of items to buffer in memory before flushing</td>
* <td>Enable/disable debug mode</td>
* <td>The consumer to use for writing messages</td>
* <td>An array of custom consumers in the format array(consumer_key => class_name)</td>
* <td>The host name for api calls (used by some consumers)</td>
* <td>api.mixpanel.com</td>
* <td>events_endpoint</td>
* <td>The endpoint for tracking events (relative to the host)</td>
* <td>people_endpoint</td>
* <td>The endpoint for making people updates (relative to the host)</td>
* <td>Tell the consumer whether or not to use ssl (when available)</td>
* <td>error_callback</td>
* <td>The name of a function to be called on consumption failures</td>
* <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>In the CurlConsumer (non-forked), it is used to determine how long the cURL call has to execute.
* 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",
* '$email' => "john.doe@example.com",
* '$phone' => "5555555555",
* 'Favorite Color' => "red"
