Added functionality to simplify the initialisation of the wrapper.

These changes were primarily to facilitate Shared iPad support.

I've also set the synchronize to happen more often because the delay was too great (IMO).

Incidentally, I deliberately left calling synchronise to the host app as it's not quite as simple as "more often is better." When using the iCloud version, calls get throttled if you use it too often, which results in the save happening less often.
