LatLng from Google Maps Polygon getPath()

    var polygonBounds = polygon.getPath();
    var bounds = [];
    for (var i = 0; i < polygonBounds.length; i++) {
          var point = {
            lat: polygonBounds.getAt(i).lat(),
            lng: polygonBounds.getAt(i).lng()
          };
          bounds.push(point);
     }

When you call Polygon.getPath()^api-doc, the return is an MVCArray^api-doc of LatLng instances that represent the first path of the Polygon. You can directly get to the members of the MVCAarray in two ways:

1. Call MVCAarray.getArray, which will return the underlying JavaScript Array that contains LatLng members.
2. Use MVCArray.getAt( index ), which will return whatever is at that index in the MVCArray (a LatLng in this case). This provides you a way to setup a JavaScript for loop to iterate over the members of the array.

You can also indirectly work with the members of the MVCArray by using the forEach(callback:function(*, number)) function. In this case, you must pass a callback function that accepts two parameters:

1. The actual member element of the MVCArray.
2. The array index where that element is located.
