Base Class for a test Fixture.
Fixtures are items which possibly require setup and/or tearing down after
a TestCase, TestSuite, or the Library has completed.
Fixtures are the prefered method of carrying incremental results or
variables between TestCases in TestSuites. (Rather than using globals.)
Using fixtures rather than globals ensures that state will be maintained
when executing tests in parallel.
.. note:: In order for Fixtures to be enumerated by the test system this
class' :code:`__new__` method must be called.
