SETTE tests

The SETTE tests are a group of validation tests made on a regular basis onto NEMO to make sure that a bug-fix or development branch won't break the model. It enables to test that different configuration of the code will compile, run, are restartable and reproducible. It also enable to compare the code performances to a previously-tested-reference version of the code.

NEMO now uses SETTE on a regular basis using the git "continuous-integration".

We will continue to do it by hand with MEDUSA, at least for now, but of course, we want to benefit from all these tests to check MEDUSA the same way!
