Explore how to incorporate authorization into code samples for restricted datasets

[hudajkhan]

#1049 is about building in a code sample view. For restricted datasets, like https://earthworks.stanford.edu/catalog/stanford-cg357zz032, the user must be logged in as a Stanford user in order to view/download the data.

Questions to answer:

• How does EarthWorks handle authorization for the restricted GeoServer?
• Is it possible to add this authorization to the code sample?
