PointUtils.py added to deal with matplotlib inputs

PointUtils.PointsToDoubleLists(pointList): Receives a list of points
[[x0,y0],[x1,y1],...] and returns double lists of
coords[[x0,x1,...],[y0,y1,y...]]
piDA lib integrated in code

Now it’s possible to read data from the real world with piDA. However
Simulator now needs fixing.
Notes: Sampling rate can be updated on-the-fly. I still don’t know if
thats good or bad, but it’s cool.
Everything needs more testing.
