Minor cleanup; multiplication.
...
I forgot to commit after cleanup but before implementing multiplication
so this commit is kind of a mess.
Anyway, it works. :D

I guess subtraction works!?

That was easy! Add BigInts of the same sign.

That was easy...

but it breaks associativity or is it commutivity?
Anyway you can't add THREE or more things in one expression (yet)
because adding OberonInt objects returns a two-tuple.
I could adjust the semantics of ObInt to accept such two-tuples and do
add_with_carry() but that's probably more trouble than it's worth.
Just gotta be careful with math expressions, eh?

Switch to double-underscore method names.
...
Worry about type conversions later.

BigInts in terms of Oberon Ints
...
Oberon RISC has Two's Complement 32-bit ints with carry.
So far so good.
