/**
  * This runs all migrations in the migrations directory.
  *
  * Migrations allow us to add, remove, or change application settings,
  * move and transform data and data structures, etc.
  *
  * Each migration must export a function called 'run', and it will be
  * run at startup.
  *
  * Migrations will be run in order (0001.js, 0002.js, etc.) and run()
  * will ALWAYS be called at startup. The run function should check an
  * internal var called 'Migration_0001' (or whatver its name is) and
  * should not re-run itself if it's been run before.
