Ideas for API usage, with inspiration from https://github.com/mikedeboer/node-github#example and others.

// Require
var Banner = require('self-service-banner');

// Create and configure instance
var banner = Banner({
  // Required
  "host": "https://ssb-nlive.smu.ca",
  // Optional: Required only for authenticated requests (Login)
  "username": creds.username, 
  "password": creds.password 
});

// Optional: all authenticated requests will implicitly call login before, if not already logged in
banner.login(/* optionally pass the credentials as argument to login method */)
.then(function() {
  // Is logged in.
  // All subsequent requests will use this authentication.
  // Only a single session is stored for this banner instance,
  // therefore logging in again will create a new session with Banner's server
})
.catch(function(error) {
  // Could not log in. Banner occurred...
  console.error(error);
});

// Unauthenticated request
// Does not request login or user credentials
banner.terms()
.then(function(terms) {
  console.log(terms); // Array of terms
});

// Authenticated request
// Requires user credentials
// Will login before if not previously logged in
banner.weekAtAGlance()
.then(function(weekSchedule) {
  // Courses for this week's schedule
  // For the currently logged in user
});

Look into using a loader such that it would automatically load new files in a directory. See http://stackoverflow.com/a/5365577/2578205http://stackoverflow.com/a/5365577/2578205
Thus we could simply add new modules to a directory and not have to register them in the main code.
