Initial commit.

Stubs in place for listing, viewing, creating, and editing surveys.

Surveys are saved in MongoDB like so:

    > db.surveys.findOne()
    {
            "_id" : ObjectId("51d1c9f7229b46b4e9c1aa84"),
            "name" : "ewomen_2012",
            "fields" : [
                    {
                            "name" : "Conference City",
                            "slug" : "conference_city",
                            "type" : "TextField"
                    }
            ]
    }

This allows surveys to be created by the end user.
