A 7-limit planar temperaments list

Here is a list of 7-limit planar temperaments, with complexity and rms
error less than 14, and badness calculated from that (as rms *
complexity^4, which are the right dimensions to correspond to linear
temperaments) less than 10000. I don't see much of interest in the ones
with badness over 5000, but they are listed in terms of increasing
badness and you can make your own judgments. Using Minkowski's basic
theorem from his geometry of numbers would help us these to be used to
get 7-limit temperaments.
