Added the method update_attributes_without_saving.

To understand the reason, say you have this:

class Post < CouchRest::Model

  key_accessor :title, :body, :author, comments

  cast :author, :as => 'Author'
  cast :comments, :as => ['Comment']

end

comment = post.comments.first

I'd like to do

comment.update_attributes_without_saving hash

because otherwise, it would create a new document for comment, which I don't want in my particular use. I just want to update the internal comment in the post.
