title: UITableView, how do I know what Section during cellForRowAtIndexPath?
body: <p>I have a UITableView displaying a list of Cities.
  I want to separate them by State.  I can't seem to figure out how to get it to pick the right items out of my Array.
  If Section 1 (Arizona) has 2 Cities and Section 2 (California) has 2 Cities, during cellForRowAtIndexPath, Section 2, City 1 has an index of 0, even though it's the 3rd item in my array.
  I thought about just turning my City Array into a State Array, where each item holds an Array of Cities, but I still don't know what section I'm on and therefore don't know which City Array under the States Array I would need to access.</p>
