Working on computational geometry algorithm (Graham and Jarvis convex hull finding methods):
  - exposing cartesian as a `first-class` scene (drawing points an lines between them)
  - GrahamConvexHull currently as example of cartesian container
First version of Graham convex hull finding (not the prettiest code ever, but works)
