Hi All,

Here's a macro for calculating centroid of polygons (reg & nonReg) & ellipses (incl circles),
based on Michael suggestion above. (thanks Michael, it seems so obvious now)

However, it is of limited use, because it is not multi-processing; which is to say,
that it could not be wired to a faceted surface; outputting the centroid of each individual facet.

For that a dedicated node is required.
Any takers?
