[Feature Request] Dot notation support for array index position

[adueck]

With mongodb you are able to use dot notation to access not only keys in an object but also positions in an array.

Here is an example of querying for an element by array index position.

It would be great if the dot notation used in lokijs supported this as well, so we could do something like this:

var items = db.addCollection('items');
items.insert({ foo: ["abc", "def"] });
var result = items.findOne({ "foo.1": "def" });

or perhaps (departing from the mongodb syntax a little to differentiate between index x and a key named "x"

var result = items.findOne({ "foo[1]": "def" });
