title: Custom InfoWindow and Marker using gmap3
body: <p>I am using <a href="http://gmap3.net/" rel="nofollow">gmap3</a> to create a Google Map with an InfoWindow of the information I specify. It works but I want to customize the InfoWindow to be a rounded rectangle and no arrow point to the location <em>and</em> I want a custom marker on the actual location. </p>
  
  <p>How do I do this? </p>
  
  <p>(I find the docs of gmap3 to be a bit confusing.)</p>
  
  <p>Here is the JS I am currently using: </p>
  
  <pre><code>$("#map").gmap3({
  map:{
     options:{
     zoom:18,
     mapTypeControl: true,
     mapTypeControlOptions: {
        style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
     },
     navigationControl: true,
     scrollwheel: true,
     streetViewControl: true
    }
  },
  infowindow:{
     address:"Boulder, Colorado",
     options:{
     content: "Text"
    }
   }
  });
  </code></pre>
  
  <p>How would I change the InfoWindow to a rounded rectangle with no arrow and a custom marker?</p>
