    SignedWordArrays store 16bit signed integers in the range -16r8000..16r7FFF.
    They are much like WordArrays, but the values stored are signed.
    In contrast to normal arrays (which store pointers to their elements),
    signedWordArrays store the values in a dense & compact way. 
    Since the representation fits the underlying C-language systems representation
    of signed int16's, this is also useful to pass bulk data to c primitive code.

    Therefore, SignedWordArrays can be used to hold bulk data in a more compact way.
        For example:
            Array new:100000 withAll:1
        requires 400k of object memory;

        in contrast,
            SignedWordArray new:100000 withAll:1
        only requires half of it.
