* Invokes the `iterator` function once for each item in `obj` collection, which can be either an

* is the value of an object property or an array element, `key` is the object property key or
* array element index and obj is the `obj` itself. Specifying a `context` for the function is optional.
*
* It is worth noting that `.forEach` does not iterate over inherited properties because it filters
* using the `hasOwnProperty` method.
*
* Unlike ES262's
* [Array.prototype.forEach](http://www.ecma-international.org/ecma-262/5.1/#sec-15.4.4.18),
* Providing 'undefined' or 'null' values for `obj` will not throw a TypeError, but rather just
* return the value provided.
*
```js
var values = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(values, function(value, key) {
this.push(key + ': ' + value);
}, log);
expect(log).toEqual(['name: misko', 'gender: male']);
```
*
* @param {Object|Array} obj Object to iterate over.
* @param {Function} iterator Iterator function.
* @param {Object=} context Object to become context (`this`) for the iterator function.
* @returns {Object|Array} Reference to `obj`.
