+/**
+ * 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.
