This is a big change. @matsko also deserves much of the credit for the implementation.
Previously, `ComponentInstruction`s held all the state for async components.
Now, we introduce several subclasses for `Instruction` to describe each type of navigation.
BREAKING CHANGE:
Redirects now use the Link DSL syntax. Before:
```
@RouteConfig([
{ path: '/foo', redirectTo: '/bar' },
{ path: '/bar', component: BarCmp }
])
```
After:
```
@RouteConfig([
{ path: '/foo', redirectTo: ['Bar'] },
{ path: '/bar', component: BarCmp, name: 'Bar' }
])
```
BREAKING CHANGE:
This also introduces `useAsDefault` in the RouteConfig, which makes cases like lazy-loading
and encapsulating large routes with sub-routes easier.
Previously, you could use `redirectTo` like this to expand a URL like `/tab` to `/tab/posts`:
@RouteConfig([
{ path: '/tab', redirectTo: '/tab/users' }
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
Now the recommended way to handle this is case is to use `useAsDefault` like so:
```
@RouteConfig([
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
@RouteConfig([
{ path: '/posts', component: PostsCmp, useAsDefault: true, name: 'Posts' },
{ path: '/users', component: UsersCmp, name: 'Users' }
])
TabsCmp { ... }
```
In the above example, you can write just `['/Tab']` and the route `Users` is automatically selected as a child route.

BREAKING CHANGE:
Previously, route configuration took a controller constructor function as the value of
`component` in a route definition:
```
$route.config([
{ route: '/', component: MyController }
])
```
Based on the name of the controller, we used to use a componentMapper service to
determine what template to pair with each controller, how to bind the instance to
the $scope.
To make the 1.x router more semantically alligned with Angular 2, we now route to a directive.
Thus a route configuration takes a normalized directive name:
```
$route.config([
{ route: '/', component: 'myDirective' }
])
```
BREAKING CHANGE:
In order to avoid name collisions, lifecycle hooks are now prefixed with `$`. Before:
```
MyController.prototype.onActivate = ...
```
After:
```
MyController.prototype.$onActivate = ...
```
Same for `$canActivate` (which now lives on the directive factory function),
`$canDeactivate`, `$canReuse`, and `$onDeactivate` hooks.
