    That sounds good.  I'll start getting familiar with the
branch-and-bound code to see what I can add.  I may also think about
    What is your preference on consulting other GPL code?  For example,
bonsaiG (GPL) and lp-solve (LGPL) both have branch-and-bound.  In addition
to consulting the literature, I could take a look at what those codes do.
It seems to me that they're resources we might as well take advantage of,
unless there's a reason to build up everything "from scratch".  What do
you think?
