phpUnit tests branch

create the branch phpUnits, this will be the master with the tests folder - it is NEVER to be merged with master, but updated as methods are reviewed/added/deleted

If contributers then want to work with the unit tests, then they can clone this branch. Also might be useful to have the wordpress unit tests from:
http://core.trac.wordpress.org/browser/tests
