Added a system test for reading a relax 1.3 model-free results file using results.read().

This included the addition of the object_comparison() method for comparing the equality of the
contents of two objects.

Fix for the DummyFileObject.readlines() method.

The last line is empty because of the split() call, and should not be returned.

Added tests for the contents of the results file in the test_write_results() system test.

Added the final OMP model-free results file (from relax 1.3) with the simulations truncated.

Fix for the test_write_results() system test.

Modifications to the DummyFileObject class to better act as a file object.

Started to check the contents of the model-free results file from results.write().

Added epydoc comments to the DummyFileObject.write() method.

Added a close() method to DummyFileObject.

Fix for the new test_write_results() system test.
