M=delayci_module(NAME, MAXDELAY, MEMHEAP)
 Creates a fractional sample time delay for use in the Audio Weaver.  Arguments:
 Arguments:
    NAME - name of the module.
    MAXDELAY - Maximum delay, in samples.
    MEMHEAP - specifies the memory heap to use to allocate the main
              state buffer.  This is a string and follows the memory
              allocation enumeration in Framework.h.  Allowable values
              are:
              'AWE_HEAP_FAST' - always use internal DM memory.
              'AWE_HEAP_FASTB' - always use internal PM memory.
              'AWE_HEAP_SLOW' - always use external memory.
              'AWE_HEAP_FAST2SLOW' - use internal memory.  If this fails
                 then use external memory (the default).
              'AWE_HEAP_FASTB2SLOW' - use internal memory.  If this fails
                 then use external memory.
