PV_BrickWall partially zero bins

Inherits from: Object : AbstractFunction : UGen : PV_ChainUGen

PV_BrickWall(buffer,  wipe)

Clears bins above or below a cutoff point.

buffer - fft buffer.

wipe - can range between -1 and +1.

if wipe == 0 then there is no effect.

if  wipe > 0 then it acts like a high pass filter, clearing bins from the bottom up. 

if  wipe < 0 then it acts like a low pass filter, clearing bins from the top down.
