An Mnesia backed Ash Datalayer.

In your application intialization, you will need to call Mnesia.create_schema([node()]).

Additionally, you will want to create your mnesia tables there.

This data layer is extremely unoptimized, fetching all records from a table and filtering them in place. This is primarily used for testing the behavior of data layers in Ash. If it was improved, it could be a viable data layer.
