Windshaft-CartoDB

This is the CartoDB map tiler. It extends Windshaft with some extra functionality and custom filters for authentication

• reads dbname from subdomain and cartodb redis for pretty tile urls
• configures windshaft to publish cartodb_id as the interactivity layer
• gets the default geometry type from the cartodb redis store
• allows tiles to be styled individually
• provides a link to varnish high speed cache
• provides a infowindow endpoint for windshaft
• provides a map_metadata endpoint for windshaft
