/**
 * Class for operating a compressor connected to a %PCM (Pneumatic Control
 * Module). The %PCM will automatically run in closed loop mode by default
 * whenever a Solenoid object is created. For most cases, a Compressor object
 * does not need to be instantiated or used in a robot program. This class is
 * only required in cases where the robot program needs a more detailed status
 * of the compressor or to enable/disable closed loop control.
 *
 * Note: you cannot operate the compressor directly from this class as doing so
 * would circumvent the safety provided by using the pressure switch and closed
 * loop control. You can only turn off closed loop control, thereby stopping
 * the compressor from operating.
