Module used to integrate its input over time.
The output is calculated as,
output(t) = alpha * output(t) + beta * input(t).
Depending on the constants alpha and beta,
the module can be used as leaky integrator or an accumulator.
If they are set in the XML-file the constants minimum and
maximum set the allowed range of the output. It will be clipped
if it is outside the range.
