This module performs what is known as a "clamp" operation, which sets the
bounds of a signal in between a minimum and a maximum value. Anything exceeding
the bounds in either direction will be set to the closest valid value. In
other words: if x is less than minimum, set x to the minimum;
if x is greater than the maximum, set x to be the maximum.
