The digital_out constructor creates a digital_out object in the specified Three Wire Port:

// Create the Brain.
brain Brain;
// Construct a Digital Input "digin" with the
// digital_out class.
digital_out digout = digital_out(Brain.ThreeWirePort.A);

This digout object will be used in all subsequent examples throughout this API documentation when referring to digital_out class methods.
