various minor enhancements

lots of small changes..  formatting, factory methods, consolidated test ivars, formatting, eliminated redundant variables, etc, blah blah.  if you do pull it, i'll venture further with some other more functional improvements, too...

Also, axed (unceremoniously) unneeded files.  Hope you aren't too sentimental about your (empty) Info.strings.plist.  

Also, removed all Framework depedecies (in lieu of Modules).

Finally, regressed to SentestKit, as XCTest doesn't work for me (as well as many others)..  good news, all the tests pass with flying colors!

Let me know with ay questions..
