Describe the New Feature

Issue dtcenter/MET#3006 adds a new tool named Pair-Stat to read already paired forecast/observation data from input files, filter as requested, and compute/write ASCII output statistics. This logic is pretty similar to the existing Point-Stat tool, however we'll only have a single input data source rather than separate ones for forecasts and observations. The initial implementation will support two data source types:

• ASCII MPR data generated by Point-Stat or provided through Python-embedding
• IODA pairs

The specifics of the usage statement and configuration file contents are still under development, but will be noted here once they are finalized.

Pair-Stat Usage:
TDB

Pair-Stat Configuration File:
TBD

Acceptance Testing

List input data types and sources.
Describe tests required for new functionality.
