gnome.utilities.geometry
geometry package
This package has:
A few higher-level objects for geometry: a Bounding Box class and a Polygon class.
It also has some lover level code basic geometry that acts on numpy arrays of points:
i.e. a polygon is expressed as a Nx2 numpy array of float64
Some of these are in Cython for speed.

Package Contents
- gnome.utilities.geometry.is_clockwise_convex(poly)
returns True if the polygon is clockwise ordered, false if not
expects a sequence of tuples, or something like it, of the points:
[ (x1, y1), (x2, y2), (x3, y3), …(xi, yi) ]
This only works for concave polygons. See:
- gnome.utilities.geometry.is_clockwise(poly)
returns True if the polygon is clockwise ordered, false if not
expects a sequence of tuples, or something like it (Nx2 array for instance), of the points:
[ (x1, y1), (x2, y2), (x3, y3), …(xi, yi) ]
