EventManager class

This class serves as a Typed event bus.

Events can be subscribed to by calling the "on" method.

Events are distributed by calling the "emit" method.

Subscribers my unsubscrive by calling "remove" with both the EventType and the callback function that was originally subscribed with.

Subscribers will implement a callback function taking exactly one argument of the same type as the Event they wish to receive.

Thus:

on(EventCallState(),(EventCallState event){ -- do something here });
