//////////////////////////////////////////////////////////////////////////////
//																			//
//	plCommonObjLib - Base class for a library of objects that are stored	//
//					 in common pages (for now, that means Textures or		//
//					 BuiltIn pages).										//
//																			//
//// How To Use //////////////////////////////////////////////////////////////
//																			//
//	Derive from this class and override the IsInteresting function to		//
//	filter out which objects you're interested in. Then, create an object	//
//	of this type (static is fine) before the export process begins.			//
//																			//
//	Then, when you are going to create an object in a common page, call		//
//	this lib to see if the object is already created. If so, it'll already	//
//	be loaded and ready to go, and you shouldn't create another one. Of		//
//	course, you always have the option of deleting it and creating another.	//
//																			//
//	The single biggest limitation is that objects in common pages can NOT	//
//	have ANY refs to ANY other objects in ANY other page. Otherwise, their	//
//	refs will get completely screwed up at export time. So don't do it!!!	//
