Title: Add Sancastle Custom DataSource example

This adds a `Custom DataSource` example to sandcastle. Currently it's a standalone example without an accompanying web-site tutorial; but eventually it will have a more detailed website counterpart.

I also renamed the GeoJSON files to have a geojson extension to prevent confusion.
