 * Class introduced to reduce the future pain when we remove sherlock (once we no longer 
 * support Android 2.x), and potentially to make it easier to support two versions.
 * 
 * This activity inherits from SherlockListActivity; there is no matching class in the
 * compatibility library.
 * 
 * It is very tempting to take the code from 'ListActivity' and base this class off of
 * BookCatalogueActivity, but currently there is little value in doing go.
