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)

Class protocol:

 elementByteSize

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

 maxVal

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

 minVal

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