When executing the scaffold application, we can push SQL changes to the database.
Currently SQL tables can be created, as that is a simple query to execute.
However updating a table, like adding new columns in place is much more complicated and has not been implemented.
Write the functionality that would allow us to push table changes and updates to the SQL database.
Add command-line args so we can change the functionality to "block on possible data loss" or not. By default it should be true.
