  * This project should give an insight in how a project might utilize the
  * programable API.
  *
  * This assumes we have a simple web project, which should initialize the
  * database by itself. There are further examples on how to control and use the
  * API in the cli project. This is the straightforward usage of db-migrate.
  *
  * You may also find a better integrated version of this with custom configs
  * and other supported features in the server.js example.
