Description:


SignedLongIntegerArrays store 64bit signed integers in the range 
16r-8000000000000000..16r7FFFFFFFFFFFFFFF.
In contrast to normal arrays (which store pointers to their elements),
signedLongIntegerArrays store the values in a dense & compact way. 
Since the representation fits the underlying C-language systems representation
of signed longlong's, this is also useful to pass bulk data to c primitive code.
(the system makes certain, that the first longlong is aligned as required)

[memory requirements:]
    OBJ-HEADER + (size * 8)


[caveat:]
    should probably be renamed to SignedInt64Array

Class protocol:

queries
o  elementByteSize
for bit-like containers, return the number of bytes stored per element.
Here, 8 is returned

o  maxVal
the maximum value which can be stored in instances of me.
For SignedLongIntegerArrays, this is 9223372036854775807 eg. 16r7FFFFFFFFFFFFFFF
(largest 64bit signed int)

o  minVal
the minimum value which can be stored in instances of me.
For SignedLongIntegerArrays, this is -9223372036854775808 eg. -16r8000000000000000
(smallest 64bit signed int)
