title: Subclassing MKOverlayPathView to create MKPolylineView
body: <p>Has anyone attempted to subclass <code>MKOverlayPathView</code> in order to, essentially, recreate <code>MKPolylineView</code> with more control of the path drawing? If so, would you be willing to share some example code?</p>
  
  <p>I want to draw an <code>MKPolyline</code> on a map view but <code>MKPolylineView</code> does not offer enough flexibility in how the path is drawn. For instance I want to add a stroke and highlight on the line like the routes seen in the Maps app.</p>
