integrate FiveAM into test package def. and main testing file.

This builds on the initial set-up in the .asd file. With the .asd file
knowing the tests package needs FiveAM, the code here integrates the
testing framework in to the .lisp files responsible for housing the
tests.

The code here is placeholder tests and should be deleted the more I
get into the project. They exist just to make sure everything is
set-up properly between the various definition/set-up files.
