Added the Ping Pong Delay Example, but it has some issues.
Changed tempFile to csdFile which is much more descriptive.
Corrected file headers to show the license information.
I've also added the Harmonizer example to the OSX project to help with the audio in debug process.
Removed logging of slider value changes.
Removed the CoreAudio related stuff from CsoundObj and use Csound's rtauhal driver as-is. Coded by Steven Yi.
Implemented a BaseCsoundWindowController at Stegen Yi's suggestion.
Merge pull request #358 from aure/AudioInTest
