Title: Adding `collectionKey` option to fix issue #31

I needed to have a link from a child collection to a parent model, so I added an option to do so, and turned it on by default. I've also updated the README file and added tests. Please review and pull in!

Note that since this is adding a new, backwards-compatible feature to the project, the minor version of the project will need to be updated from the last release, as specified by [Semantic Versioning](http://www.semver.org)
