 * for proper operation.  Thenceforth, this  class can be used to monitor
 * and manipulate the trigger functionality of the indicated camera.
 *
 * This is basically a sematics wrapper over C1394CameraControl.  The min
 * integer value is really a bitmask, and the value bits in the status register
 * map to mode and parameter
