documentation

    SignedIntegerArrays store 32bit signed integers in the range -16r80000000..16r7FFFFFFF.
    In contrast to normal arrays (which store pointers to their elements),
    signedIntegerArrays store the values in a dense & compact way. 
    Since the representation fits the underlying C-language systems representation
    of signed int32's, this is also useful to pass bulk data to c primitive code.
