This PR adds two features:

  1. Add -s- and -B flags to nccmp

-s : report when files are the same
-B: Load entire variable to memory to reduce memory allocation runtime overhead

  1. Add the capability of processing nccmp for multiple output files (e.g. from npp and n20) for the same obs type (e.g. atms)
    nccmp testrun/gdas.t00z.atms_npp.tm00.nc testoutput/gdas.t00z.atms_npp.tm00.nc
    nccmp testrun/gdas.t00z.atms_n20.tm00.nc testoutput/gdas.t00z.atms_n20.tm00.nc
