create alias greek_key -> meandros
Greek key is just another term for meandros.
https://en.wikipedia.org/wiki/Meander_(art)
There are many kinds of keys/meanders in greek art but the terms are not specific enough to be distinct.

I think it's worth aliasing because I searched for greek key before going through the wiki pattern list to find the right term.
