cime issue 146 and relevant follow-on issues have now been addressed, so it should be relatively easy to add a new test type like this.

In addition to doing a basic test, as suggested in the original comment, it could also be useful to include a transient test that has some columns (probably crop columns) going back and forth between non-zero-weight and zero-weight a few times (when they're non-zero-weight, they should stay that way for a few years to allow crops to actually grow). I think we'd expect final gridcell-average results to be the same regardless of whether the crop column stayed active or went inactive when it had 0 weight. This could be done with a single-point test. The point of this would be to catch problems with columns/patches going from active to inactive to active, as in #209 . However, catching these problems may rely on having the transition from active to inactive happen in the middle of the growing season.
