PID Controller.

A PID controller, supporting the Controller interface. Any public values are safe to modify while in operation.

p_gain, i_gain and d_gain are the respective gain values. The controlller internally stores an already adjusted integral, making it safe to alter the i_gain - it will not result in an immediate large jump in controller output.

i_min and i_max are the limits for the internal integral storage. Similarly, out_min and out_max clip the output value to an acceptable range of values. By default, all limits are set to +/- infinity.

d_mode The DerivativeMode, the default is OnMeasurement.
