/*
 C backend and module description:
    - in -os mode:
        - subcontainers are merged in the main class
        - CScalarOneSampleCodeContainer1 (used in -os0) separates the DSP control state in iControl/fControl (possibly to be allocated elsewhere)
        - CScalarOneSampleCodeContainer2 (used in -os1) separates the DSP control state in iControl/fControl and the DSP state in iZone/fZone (possibly to be allocated elsewhere)
        - CScalarOneSampleCodeContainer3 (used in -os2) separates the DSP control state in iControl/fControl and the DSP state in iZone/fZone (possibly to be allocated elsewhere). Short delay lines remain in DSP struct, long delay lines are moved in iZone/fZone.
        Additional functions 'instanceConstantsFromMem' and 'instanceConstantsToMem' to copy iConst/fConst variables from/to memory are generated.
        - CScalarOneSampleCodeContainer4 (used in -os3) is similar to CPPScalarOneSampleCodeContainer3, but iControl/fControl and iZone/fZone pointers stay in the DSP class. The -mem option uses the memory manager to allocate/destroy the iControl/fControl and iZone/fZone pointers
