Seed points using a grid.
This class seeds the polygons with Control Points by creating a grid centered on the polygon. For each grid square, if it contains any overlap, a box is then created within the grid square, surrounding the valid data. The point checked is the center of this box, and if this point is within the overlap polygon then this point is returned, otherwise the grid square does not have a point.

Return the minimum allowed area of the polygon.
This value is set from the "MinimumArea" keyword in the PVL. The seeding algorithm will not seed polygons that have an area less than this.

Return the minimum allowed thickness of the polygon.
This value is set from the "MinimumThickness" keyword in the PVL. The seeding algorithm will not seed polygons that have a thickness ratio less than this
