--------------------------------------
Great! Agree the method can and should be implemented more efficiently.
No hurry, thanks!

> When a polygon contains three consecutive points which are nearly co-planar,
> the polygon factory may fail to recognize the concavity/convexity of the
> polygon. I think the problem is the way the sideness for a polygon edge is
> calculated. It relies in the position of the next point in respect of the
> previous polygon edge which fails on the case explained above because of
> numerical imprecision. The result is that sideness is messed up.
