short scales

Moves notation gives us a handy notation for those scales some call "symmetric", or "synthetic", or "modes of limited transposition", at the same time as enlarging the family to include those that don't necessarily stack inside a whole octave. Thus the chromatic scale becomes {1}, the whole tone scale becomes {2}, diminished {2 1}, augmented {3 1}. The difference between a short scale and a loop is that the wiggly brackets here mean "keep stacking this packet of intervals on top of itself".
