Class NGonCellType

Cell type for a regular polygon with n sides. The CellDirs are simply the numbers 0 to n-1 with dir 0 being to the right. The CellRotations are the numbers 0 to n-1 for a CCW rotation of that many sides, plus numbers ~0 to ~(n-1) for the reflections, where rotation ~0 has dir 0 as a fix point.

The canonical shape (for use with deformations) is a regular polygon with incircle diamater 1.0 in the XY centered at the origin, with normal pointing Z-forward.
