tiny bit of clean up
max delay time on feedback comb filter
cleaning up AMSynth and testing
Sampler: exponential scaling on filterEnv
removing Mono from stereo effect

(will need to run single channel signals through a panner or mono node
if connecting to stereo effect)
sending synth through mono before chorus
keeping reference to Float32Array

potentially causing crashes (trying to debug)
created ScaledEnvelope as its own class

factors out the scaling from the amplitude env and normal envelope
updating examples to new ScaledEnvelope
Using ScaledEnvelope for filter envelope
optimizing comb filters

also trying to get them to crash less often. (i think it worked)
Tone constructor accepts input/output num as param
using Tone constructor in signal classes
small object count optimization
small reorganization
new class PanVol. combined Pan and Vol

useful for making stereo mixer-type things
testing new components
