2015-04-20	added filter streams adapted from ChucK and revised wave form functions	Robin Haberkorn	1	-19/+373
	* LPF, HPF, BPF, BRF filters are 2nd order Butterworth filters. Derived verbatim from ChucK's implementation. This can probably be optimized by caching the tan/cos functions. Also, they do not yet handle frequency streams shorter than the stream to filter. * Basic wave forms are now Stream methods to allow concatenative style of FM synthesis (or LFOs). To generate e.g. a sine wave with constant frequency, you can still write Stream.SinOsc(440); or tostream(440):SinOsc()
2015-04-11	added custom interactive Lua interpreter for evaluating applause expressions	Robin Haberkorn	1	-1/+1
	* implements Stream:play() using Jack as the audio backend
2015-04-09	additional useful stream operations	Robin Haberkorn	1	-13/+54

2015-04-07	replaced co-routine based implementation with closures	Robin Haberkorn	1	-72/+153
	* this improves performance by 10 times (both lua5.1 and luajit) * also, when using luajit, there appears to be little peformance loss when using stream compositions instead of maps (which are sometimes even slower!?)
