Examples
Iterate over an array

iter.next();>>> {index: 1, value: "b", done: false}
iter.next();>>> {index: 2, value: "c", done: false}
// There is no next item, so 'done' is true
iter.next();>>> {done: true}
Iterate over an object
var obj = {a: 'x', b: 'y', c: 'z'},
iter = new Iterator(obj);
iter.next();>>> {index: 0, key: "a", value: "x", done: false}
iter.next();>>> {index: 1, key: "b", value: "y", done: false}
iter.next();>>> {index: 2, key: "c", value: "z", done: false}
