Detailing out some trivial knowledge about XOR-s

____________________________
in the next :: to find -- the analytical
method for converting the 2-XOR into
the 4x NAND implementation -- is
somewhat a tricky task.

+ some correlations with 3-xor
// the analogy with the 2-xor's
NAND-s only v. seems not to
