Also, I corrected a few typos in the documentation.

Say which test data are used by your module

It uses the commit_amico test data.

I updated the tests for the new reconst/freewater module! Should be ready to re-review @Manonedde @gagnonanthony @arnaudbore

Nice job! 😄 I added minor comments. It also seems that snapshots aren't generated for the output files (other than the kernels).
