Avram::Migrator::Migration::V1

Same as #up except calls rollback method in migration.

Unless already migrated, calls migrate which in turn calls statement helpers to generate and collect SQL statements in the @prepared_statements array. Each statement is then executed in a transaction and tracked upon completion.

This macro will tell the migration to run all prepared statements outside of a transaction. This is considered "unsafe" as improper SQL could pose risk to data integrity if not handled correctly
