// ILoader.h
//
//	Abstract class that defines the interface for all loaders
//
//	A loader is used like this:
//		* open is called in order to do any necessary intialization when opening
//		a file or folder (for example, reading a zip header).
//		* load is called once for each file to load. Load should return 0 if
//		it can't load the file, or a pointer to the allocated memory (the 
//		memory should be deallocated by the caller).
//		* if the file was loaded, dispose will be called.
//		* close is called in order to do any necessary cleanup.
