participant Browser
The client accepts a form input from the user, which sends a post request to the server.
participant Express
The Express Server has a route such that when a post request is received, a call to the MongoDB database is made, and if a database is not in place, one is instantiated.
participant Mongo
MongoDB acts on the method:
albumCollection.insert({ name: req.body.album_name });
and inserts the user's input into the database as the req.body.album_name.
