added test description files for all tests currently present in functional_test_frame_work

functional_test_frame_work needs test description files

issue #2

[hsorby]

When I used the functional test framework with the proposed database I had 21 tests fail out of 37. We only want to add tests that pass and to keep those tests passing when changes are introduced into the database.

These tests failed:

	  1 - active_contraction (Failed)
	  6 - pycantilever (Failed)
	  7 - pycantilever_growth (Failed)
	  8 - pycellml_growth_law (Failed)
	  9 - cellml_split_reaction_diffusion_equation (Failed)
	 13 - pydof_constraints (Failed)
	 14 - pyfsi_2d_obstacle (Failed)
	 15 - pyfsi_tube_flow (Failed)
	 16 - pyhermite_prolate_spheroid_mechanics (Failed)
	 17 - pyhomogeneous_pipe_axial_extension (Failed)
	 19 - pylaplace_equation (Failed)
	 20 - pyleft_ventricle_inflation (Failed)
	 23 - pymonodomain_2D_HH (Failed)
	 24 - pymonodomain_2D_vary_parameters_spatially (Failed)
	 25 - mooney_rivlin_cellml (Failed)
	 26 - pynavierstokes_coupled1d0d (Failed)
	 27 - pynavierstokes_liddrivencavity (Failed)
	 28 - pynavierstokes_poiseuilleflow (Failed)
	 30 - poiseuille_static (Failed)
	 33 - stokes_ale (Failed)
	 37 - pyuniaxial_extension (Failed)

and shouldn't be added at this time.

There are 2 tests that actually fail, because the FSI code is currently being merged in by @chrispbradley and should be available soon.

For the rest of the failed tests that you are seeing, there are two answers:

1. The Python tests fail if the Python bindings for OpenCMISS-iron are not created correctly.
2. The other tests fail because input files are not found. Here I would propose having an additional data base for all input files, such as meshes, xml, cellml files, etc. See OpenCMISS/functional_test_framework#4

I have modified the OpenCMISS-Examples/active_contraction codebase to accept arguments (in a PR at the time of writing). This change enables the example to successfully pass the functional test frameworks testing criteria.

Enabling the examples that cannot accept arguments for input files is the first step in adapting the examples that fail due to input files not being accessible.

The reason for the failing Python tests is a concern. I don't quite understand how the Python bindings for Iron are not created correctly. That seems like quite a serious problem if it is the case.
