@ShortDescription

@ParamDescription(coef)
/* Allpass Coeff */
Sets the coefficient of the of the all-pass filter. 

@Description
#name provides an adjustable high-order all-pass filter. When the #param(coef) is 0, 
the filter acts as a pure single sample delay. As the 
#param(coef) is adjusted away from 0, the phase shift becomes more and more non-linear
as a function of phase. The #name can be used to implement a phase equalizer and is also
useful as a reverb building block.
