Detailed Description

Loads objects from plugins.

This class acts sort of like a CORBA ORB, except for GAUGE plugin objects. (Disclaimer: I've never used CORBA, so I don't actually know how a CORBA ORB works. Let me know if that last statement was wrong.) The class loads plugins and queries them to see what objects can be loaded from them, and what functions those objects can perform. It then fields requests for objects that perform certain types of functions by matching the request with a plugin object that performs the task and getting an instance of the object from the corresponding plugin.
