Started demodulator class based on rtl_fm.c
testing fm demodulation
Now plotting spectrum and demodulated FM
Added OpenAL /w audio init test
Now playing FM through OpenAL!

great success!
Adding buffer and testing demod functionality
experimental liquid-dsp testing
more liquid dsp experiments
moved liquid header
filtering / fm demod experiments
Experimenting with FM demod options
new demod test

working but frequency seems to be shifted?
minor variable changes

demodulated frequency still shifted by about half?
Pitch issue fixed, OpenAL weirdness

Might be time to retire OpenAL -- is behaving strangely on output
stream..
Removed OpenAL and now using PortAudio
PortAudio adjustments for OSX

Seems to be some sort of audio init race condition, intermittent crash
on startup
Moved demodulation code into it's own class

Preparing to make it more dynamic, able to tune multiple frequencies at
once and support remaining demodulation modes (AM, USB, LSB)
Merge pull request #2 from cjcliffe/demod_experiment_buffering

Demodulation experiment complete, ready to move on
