title: How to get a SortedMap from a ContentQueryMap?
body: <p>To <strong>cache</strong> a result of a Cursor, I use a ContentQueryMap.</p>
  
  <p>The fact is that I think that for every ContentQueryMap I can get only a single column of the query... But I'm not sure about this.</p>
  
  <p>Suppose that the cursor returns 2 columns: key, value.</p>
  
  <p>I want a SortedMap so done: , , ...</p>
  
  <p><strong>Q:</strong> How get that SortedMap starting from a Cursor thet select two columns, passing from ContentQueryMap (because the query must be cached)? </p>
