Build: Express Routing for HTML and API

[ErikPlachta]

The following HTML routes should be created:

• • GET /notes should return the notes.html file.
• • GET * should return the index.html file.

The following API routes should be created:

• • GET /api/notes should read the db.json file and return all saved notes as JSON.
• • POST /api/notes should receive a new note to save on the request body, add it to the db.json file, and then return the new note to the client. You'll need to find a way to give each note a unique id when it's saved (look into npm packages that could do this for you).
