---------------------------------------
Thanks, Bruno! It's good to know I'm not going crazy here:-)
> Use Centroid instead of Barycenter

> In geometry, the terms "centroid" and "barycenter" are synonyms referring to
> the center of mass of a geometric object. The code currently uses
> "barycenter" when referring to the center of mass (ex:
> {{region.getBarycenter()}}). However, "centroid" seems to be used more
> frequently. For example, one is far more likely to find relevant results when
> searching Google for "polygon centroid" than "polygon barycenter". Also,
> "barycenter" has an alternate meaning in astrophysics, where it refers to the
> center of mass of two or more orbiting objects. It seems to me like
> "centroid" is a better, more geometry-focused term to use in the code.
