Quickstart Example & Description

```javascript

// Extend object literals with function properties to have a
// _super method that references the original function, instead
// of overwriting it.
// (No dependencies, but borrowed methods from underscore.js.)

var sampleObj = {
  funcProp: function(){
    return 'Hello';
  }
};

var sampleObj2 = {
  funcProp: function(){
    var originalMethod = this._super();
    return originalMethod + ' World';
  }
};

// Note just like _.extend, only the first argument is modified
var sampleObj3 = extendWithSuper({}, sampleObj, sampleObj2);

sampleObj3.funcProp(); // Hello World

```
