Example
```
isIterator(null);        // false
isIterator(undefined);   // false
isIterator("null");      // false (Strings are iterable but not iterators)
isIterator([]);          // false (Arrays are iterable but not iterators)
isIterator({
    next: function() { return true }
});                      // true, iterators must contain a "next" function
```
