Eventlib is an asynchronous event tracking app for Django. This library was
built upon the following values:

 * It must be deadly simple to log an event;
 * It must be possible to track each event in different ways;
 * Each different "event handler" must be completely separate and fail
   gracefully;
 * The event system must be asynchronous, so let's use celery;
 * The library must be extensible;
 * 100% of test coverage is enough.
