I'm now using the entire audio processing module from WebRTC as opposed to individual DSP algorithms pulled from there before. Seems to work better this way.
- Added tests (using xcode)
- Added a define to enable callback-based audio I/O instead of using actual audio devices
- Fixed a crash on Windows when there's no access to the microphone
- Misc fixes
- Refactored audio I/O to allow sharing a common context between input and output, for those OSes that require this
- Rewritten periodic operation handling to use a "run loop" thingy instead of an ugly loop formerly known as tick thread
- Fixed a bunch of compiler warnings (closes#13)
- Added automake so you no longer need to use the GYP file for standalone builds (closes#43)
