title: Mapbox.js set map default zoom option
body: <p>I have a mapbox.js map but the parameter <code>zoom</code> doesn't seem to be doing anything
  and I can't figure it out in the documentation. whatever I set <code>zoom</code> to the zoom level always defaults to my project zoom level Here is the code:</p>
  
  <pre><code>&lt;script src='https://api.tiles.mapbox.com/mapbox.js/v1.6.1/mapbox.js'&gt;&lt;/script&gt;
  &lt;link href='https://api.tiles.mapbox.com/mapbox.js/v1.6.1/mapbox.css' rel='stylesheet' /&gt;
  
  $(document).ready(function() {
          var map = L.mapbox.map('map', 'nhaines.hek4pklk', {
              zoom: 1
          });
  
          // disable drag and zoom handlers
          map.dragging.disable();
          map.touchZoom.disable();
          map.doubleClickZoom.disable();
          map.scrollWheelZoom.disable();
          // disable tap handler, if present.
          if (map.tap) map.tap.disable();
      });
  </code></pre>
