Core Data is great but automatic migrations can be tricky. Migrations can take a long time, which could
result in [your app being terminated](http://stackoverflow.com/questions/13333289/core-data-timeout-adding-persistent-store-on-application-launch) 
if it is happening on the main thread during application launch. Performing migrations on a background 
thread is also a [bad idea](http://stackoverflow.com/a/2866725/503916), meaning your application really
needs to be able to fully launch *without a Core Data stack whatsoever* in order to safely migrate. 
This can be a huge change to make to an existing app.

If you're really only using Core Data as a cache, you don't actually *need* to perform a migration. 
Simply check if the existing store is compatible with your managed object model and if so, delete
