[David Grohmann]

Are the new friend operators supposed to return a reference to a
biginteger(like the old ones), or a biginteger itself.

The only operator that returned a reference on assignment 2 was the
assignment operator. Generally you can only return a reference if you
are returning something that was passed in to the function, so it's
not possible to return references on the +/- operators.
