 Creating an instance of this **class** configures the specified *pin* to output a 50 Hz PWM signal, which is suitable for controlling most Servo Motors.  There are three forms of the constructor: one with just a single argument; one with two arguments; and one with all six arguments.  Arguments, along with their defaults if left unspecified, are as follows:
