New Use Case: Multi-Variate MODE

[JohnHalleyGotway]

Describe the New Use Case and Enhancement

dtcenter/MET#1184 added initial support for multi-variate MODE in MET version 10.1.0. This was finalized at the end of the development cycle which didn't allow for corresponding development in METplus. This issue is to address that for METplus version 5.0.0. This issue is defined as both an enhancement and a new use case. Recommend the following:

1. Decide whether we should enhance the existing MODE wrapper or just write a new one for multi-variate MODE.

2. Enhance the wrappers to support multi-variate MODE:

• Handle the specification of multiple input variables from, potentially, multiple input files.
• Add support for the new multivar_logic = "#1 && #2 && #3"; configuration option.
• Note that "fcst_file" and "obs_file" are replaced by "fcst_file_list" and "obs_file_list" which are ASCII file lists of input files to be used.

3. Add a new use case to demonstrate one or more examples of running multi-variate MODE. It will likely need to:

• Run multi-variate MODE to generate forecast and observation "super" objects.
• Run single-variate MODE to compare those "super" objects.

Along the way, recommend keeping track of suggestions for enhancements to feed back to the MET development team.

@JohnHalleyGotway @georgemccabe I do not have met_test permissions on mohawk for adding data for this use-case. I am happy to complete this process if you want to add me, otherwise, someone else will need to complete the data-adding process.

@hertneky, I just sent an email to RAL Help to request that you are given access to the met_test user. I copied you on the email so you should be notified when you have access.

@georgemccabe Thank you, I was added and am able to runas met_test.
