/*++ ShiftArrayWorker

Routine Description:

    Shifts a section of an array up or down.  If shifting
    down, the given element is lost.  For up, an empty slot
    (with an undefined value) is opened.

Arguments:

    pArray        - Array starting address
    cbArraySize   - Size of Array (in BYTES)
    cElementSize  - Size of array elements
    iFirstElement - First element to move
    Direction     - SHIFT_UP or SHIFT_DOWN

Return Value:

    None.  No error checking either.  Should compile out to
    a movememory

Notes:
    
    Call this with the ShiftArray macro which does the size
    calcs for you
