made a few changes to the method, 'newTestCase': a) commented out all language-level related logic (which was in place for the sake of omitting import statements/public modifiers when elementary language levels are selected), b) changed the test template (which is generated when a user clicks the 'file->new junit test case' option) to scala, c) commented out the code in which setup/teardown methods are optionally inserted into the test template
