Description:

SignedIntegerArrays store 32bit signed integers in the range 16r-80000000..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.

[memory requirements:]
    OBJ-HEADER + (size * 4)


[caveat:]
    should probably be renamed to SignedInt32Array

Class protocol:

 elementByteSize

for bit-like containers, return the number of bytes stored per element.
Here, 4 is returned

 maxVal

the maximum value which can be stored in instances of me.
For SignedIntegerArrays, this is 2147483647, eg. 16r7FFFFFFF (largest 32bit signed int)

 minVal

the minimum value which can be stored in instances of me.
For SignedIntegerArrays, this is -2147483648 eg. -16r80000000 (smallest 32bit signed int)
