test harness for profillic, etc.

[tedholzman]

It would probably be a good idea to refactor the tests in seqantests, quicktests, profusetests, etc. into individual unit tests within a test harness. There are (at least) two test harness packages which would work pretty quickly. CppUnit is a port of JUnit, and seems to have good support assertions at test-time. Known advantage: I'm somewhat familiar with JUnit. The Boost Test Library is another option. Known advantage: we're already using Boost and won't have to add another 3rd party product.
