The Backup/Restore sample application now provides a "restore my own
last-known-good data" button. When it is clicked the app will run the
standard public BackupManager.requestRestore() operation.
(This was the one aspect of the public API that was not previously
exercised by the sample app.)

A very simple application: one activity, with a few bits of persistent data that
are updated live by the activity. To that are added a few alternative agent
implementations, to illustrate various approaches and tradeoffs when implementing
a backup/restore agent. In particular, there are example agents that do everything
"by hand," either record-by-record or by directly backing up the app's entire
persistent data file; plus an example agent that illustrates how very easy it
is to implement the latter using the OS-provided helpers.
