duration thoughts: A non-dotted note may be offset by half its length
but not by any smaller amount.
4 2 4 okay, 4. _2 8 bad
a non-dotted note may cross of the same value, but not a larger break
4 2 4 okay, 4 8 *4 8 4 bad
Except for fixed set of patterns like 8 4 4 4 8
dotted notes: may be at the beginning or end of a division of size 2_base
perhaps may be at beginning or end of division of size base, to allow "4. 8 4" in 3/4 meter.
Or: cannot cross division larger than base
may be offset by 1/2 base...or by (multiples of) smallest dot. I want to allow things like 11/16 meter "4 4.."
