Define as an AMD and CommonJS module

[paglias]

Making Serenade define itself as an AMD or CommonJS module would be very useful and really easy to implement.

It can be achieved by wrapping the code this way:

(function (root, factory) {
  if (typeof define === 'function' && define.amd) {

    // AMD
    define(['exports'], factory);
  } else if (typeof exports !== 'undefined') {

    // CommonJS
    var target;
    if(typeof module !== undefined){
      target = module.exports;
    }else{
      target = exports;
    }

    factory(target);
  } else {

    // Browser global
    root.Serenade = factory({})
  }
}(this, function (Serenade) {

  // Code goes here

  return Serenade;

}));
