In the above diagram:

• User is a user of the coverage app.
• CoverageApp is the SCN coverage app (this project).
• AddressResolver is a module to convert a human-provided string (thus potentially containing errors) into the closest US postal street address. It still needs to be determined what data is needed and where it comes from.
• AllConnect is a module to invoke one or more calls to the AllConnect website to scrape the plan data for a given address.
