Summary: Utility class for Directories parsing.

Remarks:
	CKDirectoryParser class useful for iterating inside a directory arborescence.
	It can be used to parse only a directory looking for files with an extension filter or
	to parse a complete arborescence.
	On Win32 platforms, suffers the extension mismatches limitation : if you want to parse the *.ext files, *.exta files
	will also be listed.

Example:
	// Counts and makes a list of files with extension .cpp 
	// in a directory tree
	CKDirectoryParser MyParser(Directory,"*.cpp",TRUE);	
	
	XClassArray<XString> FileList;
	char* str = NULL;
	while(str = parser.GetNextFile()) {
		// str contains the full path of the file.
		FileList.PushBack(XString(str));
	}
