// This method is called when starting the re-ording process. You insert a blank row object into your
// data source and return the object you want to save for later. This method is only called once.
- (id)saveObjectAndInsertBlankRowAtIndexPath:(NSIndexPath *)indexPath;

// This method is called when the selected row is dragged to a new position. You simply update your
// data source to reflect that the rows have switched places. This can be called multiple times
// during the reordering process
- (void)moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath;

// This method is called when the selected row is released to its new position. The object is the same
// object you returned in saveObjectAndInsertBlankRowAtIndexPath:. Simply update the data source so the
// object is in its new position. You should do any saving/cleanup here.
