title: Label not being recognized even though jxl import and API are there
body: <p>I am trying to teach myself how to write to an excel file and just copy and pasted some code from a tutorial, and this code should work without errors as I have seen similar on several other tutorials.  So why is Label (error is: constructor is undefined) and AddCell (error is: The method addCell(WritableCell) in the type WritableSheet is not applicable for the arguments (Label)) acting up on me?</p>
  
  <pre><code> private void addCaption(WritableSheet sheet, int column, int row, String s)
        throws RowsExceededException, WriteException {
      Label label;
      label = new Label(column, row, s, timesBoldUnderline);  //error
      sheet.addCell(label); //error
    }
  </code></pre>
