A Third Coming for processing.py (a little unexpected)

Well it seem much kudos must go to Luca Damasco (Google Summer of Code student), the python mode has returned for processing-3.0 . I've just playing with it and it seems to be it might be as well to adopt an approach similar to that I settled on for JRubyArt, and explicitly create a settings method as below, and to set the sketch title in setup:-

   1 '''
   2     A wireframe box with colored edges which expands and contracts according
   3     to time-of-day.
   4     An original implementation of *hms* from http://www.gysin-vanetti.com/hms

Static sketches including "size" as might be expected do not play too well.
