C++ Polygon Namer
I made a polygon naming algorithm that can print out the full Greek name of any polygon from a 1-gon to a 99,999-gon. Note that it is pretty useless because most of the time we'd just call a 24,742-gon that rather than a dimyriatetrachiliaheptohectotetracontakaidigon. I'm pretty sure I got them right, but then again, I extrapolated most of the prefixes.
