Detailed Description

Contains all of our objects for geometry and avoids name clashes.

The polygon is a list of points that are assumed to be connected. It will have as many sides as its point count minus one. Thus there is no valid polygon with less than three points. A function that tests whether a point is inside or outside the polygon is provided.
