Description:

LongIntegerArrays store 64bit unsigned integers in the range 
0..16rFFFFFFFFFFFFFFFF.
In contrast to normal arrays (which store pointers to their elements),
longIntegerArrays store the values in a dense & compact way. 
Since the representation fits the underlying C-language systems representation
of unsigned 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 LongIntegerArrays, this is 18446744073709551615 eg. 16rFFFFFFFFFFFFFFFF
(largest 64bit unsigned int)

 minVal

the minimum value which can be stored in instances of me.
For LongIntegerArrays, this is 0
