// 000 02/01/10 Halley Gotway New
// 001 09/09/11 Halley Gotway Call set_grid after reading
// gridded observation files.
// 002 10/13/11 Holmes Added use of command line class to
// parse the command line arguments.
// 003 10/18/11 Halley Gotway When the user requests verification
// in the config file, check that obs files have been
// specified on the command line.
// 004 11/14/11 Holmes Added code to enable reading of
// multiple config files.
// 005 12/09/11 Halley Gotway When gridded observations are
// missing, print a warning and continue rather than exiting
// with error status.
// 006 05/08/12 Halley Gotway Switch to using vx_config library.
// 007 05/08/12 Halley Gotway Move -ens_valid, -ens_lead,
// and -obs_lead command line options to config file.
// 008 05/18/12 Halley Gotway Modify logic to better handle
// missing files, fields, and data values.
// 009 08/30/12 Oldenburg Add spread/skill functionality
// 010 06/03/14 Halley Gotway Add PHIST line type
// 011 07/09/14 Halley Gotway Add station id exclusion option.
// 012 11/12/14 Halley Gotway Pass the obtype entry from the
// from the config file to the output files.
// 013 03/02/15 Halley Gotway Add automated regridding.
// 014 09/11/15 Halley Gotway Add climatology.
// 015 05/10/16 Halley Gotway Add grid weighting.
// 016 05/20/16 Prestopnik J Removed -version (now in command_line.cc)
// 017 08/09/16 Halley Gotway Fixed n_ens_vld vs n_vx_vld bug.
// 018 05/15/17 Prestonik P Add shape for regrid and interp.
// 019 05/15/17 Halley Gotway Add RELP line type and skip_const.
// 020 02/21/18 Halley Gotway Restructure config logic to make
// all options settable for each verification task.
// 021 03/21/18 Halley Gotway Add obs_error perturbation.
// 022 04/05/18 Halley Gotway Replace -ssvar_mean with -ens_mean.
// 023 08/15/18 Halley Gotway Add mask.llpnt type.
// 024 04/01/19 Fillmore Add FCST and OBS units.
// 025 04/15/19 Halley Gotway Add percentile thresholds.
// 026 11/26/19 Halley Gotway Add neighborhood probabilities.
// 027 12/11/19 Halley Gotway Reorganize logic to support the use
// of python embedding.
// 028 12/17/19 Halley Gotway Apply climatology bins to ensemble
// continuous statistics.
// 029 01/21/20 Halley Gotway Add RPS output line type.
