These are (or will soon be) a bunch of mixins for statr.

When using the mixins the are to be included in the mixins list of the new state like so:

new class fooState extends State
    mixins: [RoutedState, NamedState]
    route: 'foo'

If you are only using a single mixin you can also use it like this:

new class fooState extends State
    mixins: RoutedState
    route: 'foo'
    statename: 'foo'
