Added test cases for testing issue #53

@melodydong This looks great, especially the documentation!!

I added automatic result testing in 31a6021. Can you add your tests to the testing framework in test/run_tests.py? Let me know if you have any questions on how to do that.

After that I think it's ready to merge. Thanks for your help!

Thanks @melodydong for adding these comprehensive tests to the framework! It fails currently, but I think that's only minor notation. I can fix that.

I've seen that the test bifurcation_RCR tests quantities to 10% tolerance. Is there a reason why the tolerance is that high in that specific test?

@mrp089, thanks for fixing the notation. For the bifurcation_RCR test, I found that the 1D solver as is, was only comparable within that 10% tolerance. It's possible that it would be closer if I wrote out more steps during the simulation to exactly capture the true max and min, though I didn't explore that possibility. It could also be that the 0D rcr results interpolated the inflow slightly differently. I think the 1D solver is solving the RCR boundary conditions correctly and it might just be slight differences in interpreting the max/min values or the sensitivity of the max/min values between 0D and 1D.
