Watch for an event, identified by its class' identifier. If a callback method is provided, then it will call that method on the caller of watch
when the event happens. Otherwise, it will run the callback block.
@param identifier [Symbol] the event's identifier @param callback_method [Symbol] one option for adding a callback–the method on the object to call when the
event fires
@param callback [Block] the other option for adding a callback–the block you wish to be executed when the event
fires
@return [Proc] the block that will run when the event fires
