jUnit Tweaking

Most of the jUnit tests that I broke should now be able to compile.
Getting the tests to show green is another story though. I'll get to
that next
More jUnit tweaks

The elevator tests have all been completed and run to completion. Floor
tests are almost done. The following tests still need to be done:

Remove people from elevator - FloorTest
Summoning an elevator - FloorTest
All tests relating to the ECM and its impl (including factories)

We may want to look into adding tags in the xml file for tests. We
shouldn't have to hard code any values in our jUnit tests if we don't
have to.
