Small changes done at the end of the master.

Mostly differences in case sizes, extra output statements, not building the cartesian folder etc.

New files are a few stored diff results, the unstructured unit tests because of their requirement of the large grid, a debug version of the heateq, some benchmark autogenerated results, etc
