> Assume that every API call can fail.  We need a reliable error handling and retry  mechanism.  Upon an API call failure, we let the user retry the last task that failed.
> Page refreshes need to be handled.  At any point in time, the user should be able to hit refresh and not cause adverse affects. 
> Checkpoint at appropriate points using the "persist" call, so that we know what API calls have been executed already and we don't call them again.
