splitting out validate_* packages to testing.rb, first implementation of parse_ls_string()
bug fixing after testing in parse_ls_string
not sure i like breaking with the ruby pattern of ? methods returning true|false, but returning false or a populated hash will still meet most cases, unless you're looking for exactly 'true'
implemented several file tests, working on issue #7
whoops, wrong method name there..
implementing is_in_path?, more issue #7
