// Description:
// This class contains the primitives which are sent as a list to the RODs. They control 
// almost all aspects of the ROD DSP behavior. New primitives can be defined to perform
// user-defined actions, but corresponding DSP code must also be written, compiled and
// loaded into the DSPs before the primitive can be executed.
