title: How do I add section titles in a UIPickerView?
body: <p>This is by no means a needed thing. It would be nice if possible. I am not sure if this can be done. </p>
  
  <p>I have a <code>UIPickerView</code> and it will have 41-42 options. Right now I have all of my options alphabetically. I want them to be broken into groups and before each group I want it to have a title. Similar to how a TableView has sections and you can give each section a title. I want the title of each section in the picker but I don't want it to be a selectable row. For example: </p>
  
  <p>Picker options:<br>
  Core (not selecteable)<br>
  Barbarian (selectable)<br>
  Bard (selectable)<br>
  several more options<br>
  APG (not Selectable)<br>
  Alchemist (selectable)<br>
  Cavalier (selectable)<br>
  several more options<br>
  continue with several more </p>
  
  <p>Is this even possible? </p>
