/**
 * This class is an EventEmitter with support for wildcard event handlers.
 *
 * What this means is that you can emit events like this:
 *
 *   emit('change:firstName')
 *
 * and listen to this event like this:
 *
 *   on('change:*')
 *
 * A few notes:
 *
 * - Wildcards only work at the end of an event name.
 * - Currently you can only use 1 wildcard.
 * - Using ":" as a separator is optional, but it's highly recommended to use
 *   some kind of separator.
 *
 * The WildcardEmitter is a bit slower than the regular Emitter. If your code
 * must be very high performance, it might be better to try to use the other
 * emitter. For most usage the difference is negligible though.
