attempt to start merging new world and old renderer
documentation
simplification of code, split between render and audio source
more simplifications
simplified version; audio flow somehow works
make multiple sinks work, render with new world

no reflectors and absorbers yet
only omni and cardioid sink yet
support for higher order ambisonics (3h3v and 3h0v)
preparations for size limited diffuse source processing
more preparations for size-limited diffuse sources

complete implementation, but does not work yet
Signed-off-by: Giso Grimm <g.grimm@uni-oldenburg.de>
implemented diffuse source rendering with distance model
visualization reanimated, audio player added
preparation of door model
door - source type implemented and roughly tested
nearest speaker panning sink added
use mirror sources (still infinite size reflectors)
mirror source model working with very basic refraction model
osc positioning code simplified, preparation for generic osc scene
common osc message handling, multicast server
test files
