    * Reorganization of code..
    * Cleanup some pointless/redundant functions
    * Comment with some useful descriptions of what things are doing
    * Fix the Test Pulse Power {Up,Down} Tests: It was powering down in both
      cases (in the original PASCAL code as well)
Addition of Oscilliscope manual test-pulse check (still untested)
Some changes to testerboard.py
    * Lots of additional comments, addition of test info screen
    * Rewriting of several functions to have much more sensible flow control
