Encapsulate the helper functions in mjsunit.js. Now only exposes the exception class and the assertXXX functions. Make assertEquals use === instead of ==. This prevents a lot of possiblefalse positives in tests, and avoids having to do assertTrue(expected === actual) when you need it. Fixed some tests that were either buggy or assuming == test.
