Iterates over elements of collection invoking iteratee for each element. The iteratee is invoked with three arguments:
(value, index|key, collection). Iteratee functions may exit iteration early by explicitly returning false.
Note: As with other "Collections" methods, objects with a "length" property are iterated like arrays. To
avoid this behavior _.forIn or _.forOwn may be used for object iteration.
