Migrate API

You can think of this migrate as the "CTools for Migrate"

This module provides generic functionality for Migrate in contrib and helper services that can be used by runners, UI's and more. It will primarily be a dependency of another Migrate module in contrib and not installed on its own unless you're writing custom code around Migrate tooling.
