Adding a demo app
Demo app UI
Added a waveformView to the app delegate

Won't connect in IB for some reason, will look at it later
Just can't get this view connected
Fixed a little bug in the transformer that was making the y scaler work backwards
Test app, not working at present
Reorganize
Some tweaks, this works for the small test files but seems to fail for normal-sized files
Twiddle to clear up warning
Resize options
sorta works, very slow on larger files
Some dispatching to improve responsiveness, much more work needs to be done though.
Some more refactoring to get the hot code in a good pace
More refactoring
Some more refactoring
Progressive waveform loading seems to work
