Cleaned the methods/functions indicating if a point is in a polygon
In general, shapely should be used, especially for lots of points:
from shapely.geometry import Polygon, Point
poly = Polygon(array([[0,0],[0,1],[1,1],[1,0]]))
p = Point(0.5,0.5)
poly.contains(p) -> returns True
poly.contains(Point(-1,-1)) -> returns False
You can convert a moving.Point to a shapely point: p = moving.Point(1,2) p.asShapely() returns the equivalent shapely point
If you have several points to test, use moving.pointsInPolygon(points, polygon) where points are moving.Point and polygon is a shapely polygon.
