Fixes to getDisplayString methods & start adding some tests. First attempt (unfinished, doesn't compile)
w/ ScalaMock.  A little refactoring also.
Move files.
Attempting to use jmockit without testng or junit but it always gets
"java.lang.IllegalStateException: Invalid place to record expectations",
which is because scalatest would have to be supported like junit/testng
are, and the author accepts such patches but it would likely not be
simple.  So saving here for reference but will try mockito next.
Use mockito to create some tests; fix some bugs.
Fix copyright and todos.
Little fixes: fix test failing from cli, unused methods, copyright, cmt out test.
