app.js

// ------------------------------------------------------------------------
// app.js - a generic app provided by the Express cli, updated to provide
//          routing to both the default and 'content' functional locations.
//          NOTE: This does use EJS-based templating; if you choose to use
//          something else (like Angular or React), you will need to change
//          the view engine.
