title: Calculate the best lat and lng location for a GMaps map
body: <p>I have an array with 10 different latitude and longitude numbers gathered from GMaps. I want to show all of them on the same map in the same time. What I need to achieve, is calculate the best latitude and longitude values and zoom level (or have a formula that would calculate them for a certain zoom level), so that all markers are visible.</p>
  
  <p>I am able to implement a math formula into a language of my choice, but any suggestions are welcome.</p>
  
  <p>Thanks!</p>
