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:

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

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

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