ToDo:
===========================================================
- Interfaces:
  - The most important interfaces pass messages.  That should be
    expanded to all communication between Clients, TestHarness, 
    and Repository to prepare for Project #4
- Logging
  - enable flushing of child AppDomain logger from primary
    AppDomain via a remote object
- TestCode
  - replace all test stub code with TestPackageName class that implements ITest
  - Teststub mains now create an instance and call its test() method
  - Add these to the Repository directory to load into TestHarness
  - so far this has just been done with a partial test of the logger
- Cleanup code
  - refactor LoadAndTest class into a Load class and a Test class
Done:
===========================================================
- Add postbuild to copy test dlls into repository directory
- TestHarness
  - create test directory with author-date key
- Repository
  - copy code to child AppDomain test directory
- Logging
  - log into blocking queue, use child thread to write logs
  - support Tees
