Add field in models.csv to declare base model

[bruth]

This may be a bit too specific to our use case, but declaring the base model could help to infer some things. For example, the PEDSnet data model is based on OMOP so we could rely on that for implicit mappings and add a file type to declare the diff from the base model (rather than redefining all the fields).

I suppose this would make sense, especially if we want to support the addition of data models by other parties. But I worry about violating WYSIWYG.

But I worry about violating WYSIWYG.

I generally agree with this. A more practical application would be to create a tool that copies an existing data model, increments the version across all the files and sets up the default mappings. For example, if you did data-models derive pedsnet/v1 omop/v4 it would copy all the files in omop/v4 and replace all the instances of model and version with pedsnet and v1 and add additional mappings between omop/v4 and pedsnet/v1.
