Added the missing import of the relax data storage object into the pipe creation system test.

System_test_runner.run() is no longer called with the runner argument.

Fixed the reference to the now non-existent 'pipe' variable.

Removed the unused 'runner' argument to System_test_runner.run().

Placed the relax namespace into the new system tests.

The relax namespace will now be available to all new TestCase class instances.

Bug fix for the pipe creation system test.

The __init__ function should not be overwritten! The relax instance must be passed in by some other
method.

Added the ability to run the new system/functional tests based on the unittest framework.

Added some code to execute the new system/functional tests.

This just runs the System_test_runner.run() method which doesn't do anything yet.

Renamed the pipe creation module to start with 'test_'.

Created a class called System_test_runner for executing the system/functional tests.

Whether this is replaced by Gary's Unit_test_runner, invokes Unit_test_runner, or is independent of
Unit_test_runner is not yet known.
