	PROJECT:	ResKnife
	FILE:		ResKnifeResourceProtocol.h
	
	PURPOSE:	This protocol wraps up whatever implementation the host
				application (i.e. ResKnife) uses for resources in a way that
				every editor can get enough information about the resource
				being edited.
				
				Or in Nick's immortal words (which I found only *after* I had
				written the stuff above):
				
				This protocol allows your plug to interrogate a resource to
				find out information about it.

	REVISIONS:
		2003-07-31  UK  Added document accessor, commented.
