A peek at diaschisoid/ragatonic 6561/6250

I proposed the name ragitone for 6561/6250, since it is a ragisma shy
of the 21/20 minor septimal semitone. The diaschisoid name wouldn't
work for the Fokker blocks since we had too many otheer similar names.

You can get a good Ragitonic[12] from 5/59, but the top tuning might
be interesting: [1203.324, 1896.686, 2794.033]. I may try some
retuning experiments or see if I can get something interesting which
circulates.
