WrapIndex index into a table with a signal

WrapIndex.ar(bufnum, in, mul, add)

WrapIndex.kr(bufnum, in, mul, add)

The input signal value is truncated to an integer value and used as an index into the table.

Out of range index values are wrapped cyclically to the valid range.

bufnum - index of the buffer

in - the input signal.
