implemented a push object for pushing audio into Libaudioverse rather than being pulled
Python example of push node via synthesis of binaural beats
Bump python version number to 0.1 to make wheel happy
Bound the enum for object states to Python
Improvement to HRIR normalization.

The new algorithm normalizes after the crossfade in computeCoefficientsStereo.
This provides a method by which volume decreases may possibly be avoided.
This is not time-tested, and may be rolled back.
Fixed mixer resizing
Internal: resamplers can estimate their available output
implement method for push nodes to notify on low audio
Implemented configurable protection against multifiring callbacks
Turn on multifiring protection for the push node's callback
Numerous small fixes to push object
Ignore my virtualenv
We can enumerate Winmm devices
Complete, basic winmm backend
Fix sleeping in the winmm backend
Python bindings: fixed clearing inputs
Set the 3D example's mixahead and buffer size to soemthing sensible
Add a sleep to the winmm backend to give the mixer a chance to get ahead
Properly initialize the atomic variables common to all backends
Merge branch 'master' into audio_backends
