* Interface to implement when creating a custom change that does not actually generate SQL.
* If you are updating a database through SQL, implementing CustomSqlChange is preferred because the SQL can either be executed
* directly or saved to a text file for later use depending on the migration mode used.
* To allow the change to be rolled back, also implement the CustomTaskRollback interface.
* If your change requires sql-based logic and non-sql-based logic, it is best to create a change set that contains a mix of CustomSqlChange and CustomTaskChange calls.
