> I have a customer request that we can work on several similar single-table DataContexts as if they are one. In the concrete example it's a set of CSV files all with the same headers etc.
> Similar to how METAMODEL-61 describes a DataContext with multiple CSV files in a folder, and how we currently have the CompositeDataContext implementation, this implementation would be a wrapper of other DataContexts, but offering them all in a UNION like fashion where they are virtually all part of the same table.
