wrf_moving_nest_precip.ncl: An example script to plot precipitation tendencies of moving nest domains on the same map background.

In this script note:

 - This script uses multi input files when reading in model data, but can easily be adapted for moving nests within a single output file (Although we recommend always writing moving nests to multiple files)
-  It also ensure that the plot map background stays the same
 
- In addition to this, the script finds the overlapping area between two time periods for the moving nest domain, and calculates rainfall tendencies in this area (remember rainfall in the model is an accumulative field, so the difference in this field between two times will represent the rainfall tendencies during that time).
 NOTE: if your output frequency is low, then the nest will move far between two time periods, and the overlapping area will be small, and possibly meaningless.
