Added another dependency to the project: camljs.js by omlin. This is an
open source project which makes creating CAML queries very easy. This will
be used to make querying lists very easy and will allow for easy filtering
and limiting in JavaScript.

Currently, SPE will return all items from a list and will use any filters
and selectors provided. These items are returned as native SP.Item objects
if no selectors are provided. If a selector is provided, them the returned
items are objects containing the requested fields.

TODO:

1. Add ability to create/update list items
