Graphics improvements

* Added -nomargin option
* subplots now use multiple rows, if necessary
* EtsPlot removes points for which there is no data (instead of value 0)
Unsafe use of NcVar that may be NULL

* Do a check for NULL before using variable
Fixes bug in computing inverse with discrete variables

* Configurations with discrete masses produced strange inverse values
  because P1 was used as the cumulative value not the discrete value
New plots and other improvements
* Added BaseRate, DRocNorm, OddsRatioSS
* Special precip thresholds in DRocPlot
* Added -noobs to map
