Start on set 5, code cleanup in lmwg.py, add additional functions required for set 5. Also separate out table with 1 dataset vs 2 datasets in land set5 preliminary code. This might eventually be a flag to set5 initialization instead of separate variables. Something similar needs done for set 1 as well.
Start dealing with obs and dataset 2nd fts. eventually needs extra work for 2 sets+obs cases
Add -set {number} and --plots yes support to diags.py; required some code changes in options.py
