Implemented HPS algorithm from Song Pong

Tried to tune the different parameters iterations, and the arbitrary constants
but no sufficiently good result. Still it somewhat resembles the characteristics
of the four tones but maybe the HPS algorithm is not good enough for this!?
Changed to requestAnimationFrame for animation

Currently the line has some very sharp edges and the changes in fundamental pitch are erratic. Red microphone line is not
being plotted.
Smoothed outputline

Interpolation between previous and current tone in toneView. Also changed to requestAnimationframe for the updaterate. Microphone input not working but
seems to be because of Linux incompabilities. Removed old AVG-update method
separated tones and further smoothing

Now each silent passage invokes a new drawing space. this is better instead
of having one continous line over time. the line is also thicker to be more
directly relatable. Further interpolation would be desired where the current value also depends on further historical values.
Merge branch 'HPSimplementation'

HPS is now implemented and giving an useable result. Each syllable is now
also separated. thick rounded line instead of sharp thin long one
