MR_autoMigrationOptions isn't explicitly declared anywhere, this change just makes it public since it's a useful thing to have around. I also moved where the method was in the source so it's not mixed in with the instance methods.
Add missing MR_autoMigrationOptions declaration to header.
Is there a particular reason you needed the auto migration options dictionary public? The point for making it "private" was that you really don't need that..
I'm doing a manual migration and needed the options dictionary for the migration.
I've started addressing this in MagicalRecord 3.0. It will provide a method to provide options to this process.
