//       Class : VirtualMouse
// Description : Poses as a MouseAndKeyboard object in the datagraph,
//               but accepts input from user calls, rather than
//               reading the actual mouse and keyboard from an input
//               device.  The user can write high-level code to put
//               the mouse wherever he/she wants, and to insert
//               keypresses on demand.
