Data Import System

[DMalone87]

For the purposes of the MVP, we'll need to have some system that will allow us to import data into the database from a CSV file. The importer should interpret the data and apply a filter in order to transform the unique schema that exists in the particular CSV file into something that comports with the shared schema of the index.

This system will eventually be used to onboard new data contributors in order to efficiently add past data from that contributor to the index.
