//----------------------------
// plKeyFinder 
//----------------------------
// provides a way to look up an object (via its plKey)
// Using strings.  The should only be used at Program Init time or console use (cause its not fast)
// The error codes are remembered, and used for subsequent calls to GetLastErrorString(); which can
// be display to tell the user where he screwed up the input.
// If a key is not found it returns nil

//----------------------------
// EXAMPLE OF USE:
//----------------------------
//
//	plKeyFinder *pFind = hsgResMgr::ResMgr()->GetKeyFinder();
//	plKey pKey = pFind->StupidSearch("Global", "Globalx", "1", "plSceneNode", "1");
//	if (!pKey)
//		hsStatusMessage(pFind->GetLastErrorString());
//	delete pFind;
