Summary: Utility class for filenames extraction

Remarks:
	CKPathSplitter & CKPathMaker are useful for manipulation of filenames and paths.
	CKPathSplitter class is used to break a path into its four components (Drive, Directory Filename and extension).
	CKPathMaker class creates a path string from its four components..


Example:
		// for example to change the name of a file :
		CKPathSplitter	splitter(OldFilename);
		
		char* OldName = splitter.GetName();
		char* newname = ChangeName(OldName);
		CKPathMaker maker(splitter.GetDrive(),splitter.GetDir(),newname,splitter.GetExtension());
		char* NewFilename = maker.GetFileName();
