Enhancement: Add a callback when creating markers

[GoogleCodeExporter]

Can you add a callback that allows for customized processing of the placemark 
for a marker?  I don't want to replicate everything you do, just add/change a 
few items.

perhaps, just before the infoWindow opening event handler, add a callback:

  if (!!parserOptions.pmParseMk) parserOptions.pmParseMk(marker, placemark);
   // Infowindow-opening event handler
    google.maps.event.addListener(marker, 'click', function() {
    this.infoWindow.close();
        marker.infoWindow.setOptions(infoWindowOptions);
    this.infoWindow.open(this.map, this);
    });
