Exported Polygon::getSubPolygons() to Python. 

* New: In Hurricane::Isobar::PyPolygon, export the getSubPolygons()
    method. Makes a list of list (maybe tuple should have been better
    to prevent user's rewrite).
* Change: In documentation/examples/scripts/, update polygons.py to
    serve as a very basic test-bench for Polygon, manhattanhization
    and sub-polygons display.
