 * Python methods are defined here.

 *     - A wrapper function that returns a PyObject or appropriate python type
 *     - A C++ implementation of the python method, named the same as the python call
 *     - An entry in the python methods array so the call is accessible from python

 *     py_move_systay - wrapper function
 *     moveSystray - actual implementation of method
