[chuck-users] BlitSaw.period missing

Fellow ChucKists, I just noticed that BlitSaw (and I assume the other BlitFoo's) doesn't have a .period() member for setting/getting the frequency/period based on cycle-length. I feel they should have this. This would be consistent with the other oscillators (and it's not something that is affected by their nature like -say- hard-sync is), it'd be useful and it would fit with the strongly-timed style of ChucK. Yours, Kas.
