@section{description}
Outputs one impulse each time it receives a certain number of triggers at
its input.
@section{classmethods}
@section{method}
ar, kr
@section{argument}
trig
Trigger. Trigger can be any signal. A trigger happens when the
signal changes from non-positive to positive.
@section{argument}
div
Number of triggers to count before outputting an impulse.
@section{argument}
start
Starting value for the trigger count. This lets you start
somewhere in the middle of a count. If start is negative
it adds that many counts to the first time the output is
triggered.
