Test cases.

While this does not *prove* the correctness of the code in a

mathematical sense, it does in a monte-carlo sense. I note that both

maxima and axiom have test suites.

I do not think new mathematical code or subsystems should be accepted

unless they are accompanied by a thorough test suite.
