Simplify ncremap output?

[pwolfram]

Currently, ncremap produces a ton of output each operation, e.g.,

Running remap script ncremap from directory /net/scratch3/pwolfram/miniconda2/envs/test_analysis/bin
NCO binaries version "4.6.4" from directory /net/scratch3/pwolfram/miniconda2/envs/test_analysis/bin
Input files in or relative to directory /users/pwolfram/MPAS-Analysis
Intermediate/temporary files written to directory /lustre/scratch3/turquoise/pwolfram/tmp

Input data shaped in "mpas"-order, will permute with "ncpdq -a Time,nVertLevels,maxEdges,MaxEdges2,nCategories,ONE,nEdges,nCells"
Input assumed to be MPAS-O/I data: will apply renormalized regridding (--rnr=0.0)
Source and destination grids will both be read from supplied map-file

ncks: INFO nco_fl_open() reports current extended filetype = NC_FORMATX_NC3 does not equal previous extended filetype = NC_FORMATX_HDF5. This is expected when NCO is instructed to convert filetypes, i.e., to read from one type and write to another. And when NCO generates grids or templates (which are always netCDF3) when the input file is netCDF4. It is also expected when multi-file operators receive files known to be of different types. However, it could also indicate an unexpected change in input dataset type of which the user should be cognizant.

Would it be best to simplify this output and only return the complete set of output if an error occurs? I would argue that we don't need all this output for standard analysis runs.

@pwolfram, we've already had a lengthy discussion about this while you were away in proposal land ;-) : https://github.com/MPAS-Dev/MPAS-Analysis/pull/124#issuecomment-283455450

Ok, sounds good. Thanks @xylar. I think this is something we will want to deal with long-term but following that thread it doesn't appear to be a short-term issue. I recommend we leave this issue open for now.

[xylar]

I think we want to wait for a future version of nco that allows us to suppress some of this verbose output and live with it in the meantime. I'm concerned that relevant warnings that aren't full-blown errors would be missed if I bury the output entirely for error-free runs.

[xylar]

By all means leave this issue here until we get around to updating nco to an appropriate version and setting the needed flags.
