Optimize View Frustum wire format.
- Changed View frstum orientaton to be a quaternion
- Implemented packing formats for Orientation Quats, Ratios, and Clipping values
- Changed wire format for View Frustum details to be more efficient 28 bytes vs 64 bytes
removed extra comment
Optimize wire-format for AvatarData
- moved HandState into semi-nibble in bitItems
- moved KeyState into semi-nibble in bitItems
- moved AudioLoudness into scaled float stored as byte
- overall savings - 5 bytes
working on handPosition optimizations
add the STK library for future audio magic
perform a test reverb effect
fix the parameters for hello world for FreeVerb
an initial version of distance reverb
tune the initial distance reverb effect
clear the FreeVerb object before reuse
FreeVerb effect must be set up again after clear
some refactor to re-use the FreeVerb effect
Merge branch 'master' of https://github.com/worklist/hifi
Refactor/Cleanup serial interface to use vectors, correct rotation axes.  Added translation estimation for the head.
Merge branch 'master' of https://github.com/worklist/hifi
create a FreeVerb object for each other agent per agent
Merge remote-tracking branch 'upstream/master' into synthesis
revert hardcode of birarda test machine IP to AgentList
fix use of PI constant after merge with upstream master
use iterator when looking for other agent FreeVerb for smarter memory use
