title: PHPExcel how to read cell value without interpretation?
body: <p>I'm only reading from an Excel2007 file, not writing.</p>
  
  <p>I'm looping through a RowIterator, then a CellIterator, echoing $cell->getValue() into an HTML table.  For some cells, the cell value is incorrect and appears as a number (a float, specifically) when I want the actual value (as a string).</p>
  
  <p>How do I force all cell values to be the original value without conversion into numbers and without interpretation?</p>
