Comparing two NetCDF files

nccmp compares two NetCDF files

NCCMP compares two netcdf files and prints the differences. This function is useful for testing mathematical forecasting or prediction models.

USAGE:
NCCMP(ncfile1,ncfile2)
NCCMP(ncfile1,ncfile2,tolerance,forceCompare)

INPUT:
ncfile1 - name of the NetCDF file to compare
ncfile2 - name of the NetCDF file to compare
tolerance - Compare numeric data using a tolerance threshold
forceCompare - if false, exit when first difference is found
true: continues to process all variables

EXAMPLES:
nccmp('old.nc','new.nc',0.000001)
nccmp('old.nc','new.nc',[],true)

FEATURES:
1. Print the differences and their locations
2. Exits when first difference is found or optionally continues to process all variables
3. User defined tolerance threshold to compare the variables

TO DO:
1. Specific variable inclusion or exclusion
2. Specific attribute inclusion or exclusion
3. Option to ignore the history attribute
4. Ignore difference between values that have different missing values etc
