Implemented path::is_dir and other misc path stuff

Path::is_dir simply returns 1 or 0 as to whether the complete path instance
ends in a directory.

Wrote placeholder for path::append. Just returns 1 for now.

Moved delim variable from constructor into a public class level so other
methods could share (be nice!)
