A common problem with many test suites is that they can take a long time to
run. The longer they run, the less likely you are to run the tests. This
module borrows a trick from Apache::Registry to load up your tests at once,
create a separate package for each test and wraps each package in a method
named run_the_tests. This allows us to load perl only once and related
modules only once. If you have modules which are expensive to load, this can
dramatically speed up a test suite.
