title: Zoom MKMapView to best fit distance zoom level based on list of locations
body: <p>I have a center location I want my <code>MKMapView</code> to zoom to and also a list of locations (latitude/longitude). I would like to set the zoom level (distance) based on this list of locations so that as many of these locations are visible on the <code>MKMapView</code> at the same time, but with a minimum zoom level (or max distance) so that my <code>MKMapView</code> does not zoom out to much.</p>
  
  <p>So lets say I have a list of 10 locations but one of those locations is so far away from my center location that if I show that one location on the <code>MKMapView</code> it will be zoomed out to much, how do I calculate the distance parameters for <code>MKCoordinateRegionMakeWithDistance</code>?</p>
  
  <p>I hope I explained my problem well enough, I have difficulties explaining it I think.</p>
  
  <p>Thank you<br>
