36 * TODO Use layout?  Or use the standard resources that ActionBarDemo uses?
37 * TODO Revisit the sort order when we get more detailed UI spec.  (current sort order makes things
38 * simpler for now.)  Maybe we can just use SimpleCursorAdapter.

40 * TODO We actually don't need the auto-requery.  Just refresh it when we modify accounts.
