Allow people to add/remove/invoke observers (callbacks) to any rgrl object.
This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an rgrl_ommand to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command.
