/**

 *  Creates custom command objects.

 *  Custom commands are loaded by system state manager based on DLL name and

 *  function ordinal.

 *  Each DLL containing custom commands must offer factory methods for each

 *  custom command.

 *  The function ordinals must be exactly the same in emulator and HW builds

 *  or loading the custom command may have unpredictable results.

 *

 *  DCMOCustCmdsFactory is a static class containing factory method of one

 *  custom command. It can be easily extended to contain factory methods of

 *  multiple custom commands by adding more member functions.

 *

 *  It is better to implement own factory method for each separate command

 *  than to try to use parameters of Execute function to distinguish between

 *  them.

 *  Note that similar commands can be implemented in the same command class -

 *  just the factory methods need to be different.
