Slight tidying of test files

[MichaelClerx]

All live in test now, but still separating the real life use cases from the models and protocols created just for testing

@jonc125 what do you think of this proposal for tidying up the test files? There's still a lot of unused files we could weed out at some later time

[jonc125]

Oh, actually, some of the data files are not output so we need an input subfolder too. The interpolation_test CSV files, for instance. Those are the only ones I can spot at a quick look though.

The *divisions.dat files can be removed, they were only used by cell-based Chaste C++ tests. Similarly you can remove:

• reference_traces
• sicouri_dog_ventricle
• sun_rat_ventricle
• morgan_human_ventricle
• kim_human_atrial

I've not gone through every change, but this looks reasonable and the tests pass. I'd probably have gone for a models/real structure rather than real/models but that's a minor point and subject to personal preference! What I would like to see before this is merged is a readme.md file added to the test folder outlining the structure and rationale.

Fair point! I initially had it as suite/[models|protocols|data], reasoning that this was a suite of real life test cases you could run through e.g. python_reproducibility, but then I saw we had a hard-coded selection and actually use the real models/protocols a lot in other tests...
