Iterable Object

/*
 * Programming Quiz: Make An Iterable Object
 *
 * Turn the `james` object into an iterable object.
 *
 * Each call to iterator.next should log out an object with the following info:
 *     - key: the key from the `james` object
 *     - value: the value of the key from the `james` object
 *     - done: true or false if there are more keys/values
 *
 * For clarification, look at the example console.logs at the bottom of the code.

 *
 * Hints:
 *   - Use `Object.keys()` to store the object's properties in an array.
 *   - Each call to `iterator.next()` should use this array to know which property to return.
 *   - You can access the original object using `this`.
 *   - To access the values of the original object, use `this` and the key from the `Object.keys()` array.
