[chuck-users] Dyno docs erata

The online docs ( http://chuck.cs.princeton.edu/doc/program/ugen_full.html#Dyno ) say; - *.attackTime* - ( float, READ/WRITE ) - duration for the envelope to move linearly from current value to the absolute value of the signal's amplitude - *.releaseTime* - ( float, READ/WRITE ) - duration for the envelope to decay down to around 1/10 of its current amplitude, if not brought back up by the signal The type should instead be "duration". This is slightly relevant-ish as some of the STK UGens would express times in float. I think we got most of those by now but it can't hurt to keep such confusing inconsistencies to a minimum. Yours, Kas.
