title: how to save and restore position of map in google map v3
body: <p>I used Google API version 2 in my previous assignment. There I had used <code>map.savePosition()</code> to save the current position of map and <code>map.returnToSavedPosition()</code> to restore to the saved position. I have searched for the equivalent in api version 3 documentation but could not find relevant results. And if I use <code>map.savePosition()</code> now with api-3, javascript error tells "<strong>map.savePosition is not a function</strong>".</p>
  
  <p>Can someone please tell me what are the ways to save and restore the position of Google Map in API 3 ?</p>
