+ *  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.
