Convergencetest/verbosity
- convergencetest.py now continues even if one section of the test fails. (Before, it immediately returned 1 for failure.) This feature is desirable if we have multiple test sections, say pressure and velocity in navier-stokes. We then will want to know which sections failed exactly.
- The script now always prints convergence rates, even if all test sections are passed. I found this nice to have. Might be debatable.
