CMOR fixes

[sterlingbaldwin]

Two issues exist for CMOR:

1. cmor should use the cmip6 variables names in its config var list
2. it should check the actual file names of the output not just how many files are there

I'd also add:

3. CMOR should be added to the processflow docs

Are the first 2 items bugs in CMOR? Or how processflow users CMOR? Not clear.

Its the cmor job in processflow. Right now you list the input variables names, and processflow counts the number of output variables to see if the job finished successfully, but this doesnt take into account that the relationship isnt 1-to-1. Sometimes several input variables are needed for a single output.
