Seed data should support CSV files

[jpoehls]

• CSV files must have headers that match the table's column names.
• The CSV file name must either match the table name completely (ex. MyTable.csv) or must contains the table name in brackets somewhere in the file name (ex. demo data for [MyTable].csv).
• If the headers include the Primary Key column then turn identity insert on.
• The CSV file name must include the table name in some parsable way.
• Turn off CHECK CONSTRAINT before inserts and turn it back on afterwords.
