This merge also adds ISOMIP+ test cases that demonstrate the usage of the coordinate.

In the process, a small bug was found in the ISOMIP+ visualization in which the colormap bounds were incorrectly including zero even for fields (like salinity) where this is not appropriate. This has also been fixed here for convenience.

Testing

I ran the performance and then 1 month of the simulation step in the 2km/sigma/Ocean0 test case.

The results look as expected, e.g. here is a cross section of potential temperature:
sectionTemp_0001

And here is the overturning streamfunction:
osf_0001

@cbegeman, this is ready for you to review. I think all you need to do is describe the testing you've already done (since I believe you are already using this coordinate and the sigma versions of the ISOMIP+ test cases).

Approving based on testing on chrys with intel-mpi. I ran both the included 10-layer sigma Ocean0 case and a 3-layer sigma time_varying_Ocean0 case.
