Fixes for phpunit.xml, reworking of BaseHarness to take out reference to PHPUnit library.  Currently NumberToText covered 100% with tests (two bugs fixed for extra space and incorrectly calculating very large numbers).  Other tests marked as incomplete if causing PHPUnit to fail with fatal errors.
Reworking of directory structure, added loggers for integration with Jenkins for PHPUnit, and other fixes (using backup globals, etc).
