Landgram diagnostics

A new python version of the landgram is designed to link with the ecLand v2.0 model output of the ecLand tests.

landgram.py --input "./o_*.nc" --lat 42.5378 --lon -72.1715 --loc "Harvard Forest" --out landgram_HarvardForest.png

plot the output of US-Ha1_1991-1996 experiment.

Just make sure the input namelist activates writing the output
