  # The rails analyzer does not need to set the trace func, because that is
  # done in the perversion of Test::Unit::TestCase.
  
  # Since we flip tracing on only right before a test is executed, to avoid
  # tracing the entire framework at all times (very slow), we need to pre-load
  # all of the application's models and controllers so that we can trace things
  # at the class level.  This is just easier to do than to try and figure out
  # what should really be marked as hit in the output stage.
