/*
	Create the combine object, or use the cached version

	Required Arguments:
		@enableSCache:				true: cache combined/compressed files on the server, false: re-combine on each request
		@cachePath:					where should the cached combined files be stored on the server?
		@enableCCache:				enable client-side cache (via etags and/or last-modified headers)
		@compressJS:				compress Javascript using YUI compressor or JSMin?
		@compressCSS:				compress CSS using YUI CSS compressor

	Optional Arguments:
		@outputSeperator			character to use to seperate the output of different file content (default = \n)
		@skipMissingFiles:		true: ignore file-not-found errors, false: throw errors when a requested file cannot be found (default = true)
		@getFileModifiedMethod:	'java' or 'com'. Which method to use to obtain the last modified dates of local files. Java is the recommended and default option.
