It's definitely a manpower thing - test suites would be great for the
math classes (and others, but I can't think of a nice way to test
projections just yet). The amount of time I've spent fixing apparently
trivial functions in the math classes beggars belief! I wouldn't want to
give a student a *completely* menial project like that, though it could
be part of something else. I don't have any project students next year,
though... any MCnetters who could help out with Rivet?

Really, testing needs to be part of our standard way of working. That
means it has to be relatively painless. So here's an incentive: anyone
who devotes a bit of time to looking at e.g. Boost.Test and planning how
such a framework could fit into Rivet will have earned themselves a beer
or two ;)
