Max maximum within last x samples

Max.kr(in, numsamp)

Will output the maximum value of over the last numsamp samples, calculated efficiently by storing a local maximum for every control period. The numsamp argument will be rounded to a multiple of control period lengths. The output is the held maximum at control rate. 

in- input to sample (.ar rate)

numsamp- take the maximum over this number of samples into the past (will be rounded to control periods)
