Further work making the OSX Examples parallel to the iOS examples.
Completed conversion of examples using .xib files separately for each example.
Removed -+rtaudio=null part from this csd file.
Minor code clean up.
Changed the output of these methods to void.  The output was never used and this method signature is not indicative that anything should be returned.
Removed a debugging log statement.
Restored the CsoundObj to be very much like the corresponding one for iOS, but with a few code blocks commented out.  Currently this is producing distorted buzzy overdriven sound.
