Title: View argument directives/bindings

@nciagra, @jamesmacaulay for review please and thank you!

This formalizes how to pass data to views so they can be used in an abstract manner.

If I have a view like so:
```coffee
class TestView extends Batman.View
@directiveAccessor 'keyA', 'keyB'
```

and render it in HTML like so :
```html

```

the `TestView` instance will have accessors `keyA` and `keyB` which update whenever the keypaths `one` and `two` change. Horray!
