Project cleanup

Project cleanup

1. Check that:
   1. there are no compilation errors,
   2. implemented TODO and fixed FIXME keywords are deleted (no need to delete whole comment),
   3. commented (dead) code is deleted,
   4. code is well formatted.
2. Check, that tests are passing, when called in group:
   1. open jtm.testSuite.AllTests.java file and comment out unnecessary calls to tests
   2. run AllTests.java as unit test and check results,
   3. if some tests called from AllTests.java fail, check that your programs exit gracefully. I.e. red square (Terminate) button should be disabled (also after Remove Launch button is pressed).
3. Make sure you add, commit and push changes to the server.
