Implemented a resolve-uri implementation and tests using: http://www.ics.uci.edu/~fielding/url/test2.html
All tests pass except ones that resolve src-uri and "//c". The latter url is parsed incorrectly.
removed brackets for numbering resources
added a special case for the target-uri having a url of the form "//c".
Merge pull request #9 from shriphani/master

resolve-uri takes a source and target URLs and produces a resulting absolute target-uri
