nomenclature about type, output_type, and target_type

[elray1]

Currently in the hub tasks.json, we have:

1. model_tasks > output_type, which describes a representation or summary of a probability distribution and lines up with the type column in a model output submission file
2. model_tasks > target_metadata > target_type, which describes a statistical variable type

Maybe we should have a more consistent naming for the two things in point 1? e.g., might we want to change the column name in submission files to output_type rather than just type?

Happy with this and makes sense to me.

Let me know whether to go ahead and implement .

Main changes required will be to:

• hubDocs: documentation on model-output data format
• Example hubs (both test mini-hubs in inst and any full example hubs)

This is complete in hubUtils. Still needs addressing in hubDocs but issue exists: hubverse-org/hubDocs#50.
