 The `data` should be set of key-value pairs. By default, the data is spread as
 props to the `component` and it will be merged with the `component` props.
 
-You may include Backbone models in the `data`. This is what makes it interesting.
-`.toJSON()` is called on Backbone models before passing them as props. Also,

 The `selector` function takes the `data` (with the models cast to JSON) as its
 argument and returns a new set of key-value pairs that are derived/computed
