anchor.diff:    Each definition translates to a [Route](https://angular.io/docs/ts/latest/api/router/Route-class.html) which has a
     * `path` - the URL path segment for this route
     * `name` - the name of the route
  -  * `component` - the Component associated with this route.
  +  * `component` - the component associated with this route.
   
     The router draws upon its registry of route definition when
     1. the browser URL changes
  
positive.code: :marked
    ### Configuration
    When the browser's URL changes, the router looks for a corresponding **`RouteDefinition`**
    from which it can determine the Component to display.
  
    A new router has no route definitions. We have to configure it.
    The preferred way to configure the router is with a **`@RouteConfig`** [decorator](glossary.html#decorator)
  
negative.code:   tr
      td <code>@RouteConfig</code>
      td.
        Configures a router with <code>RouteDefinitions</code>, each mapping a URL path to a component.
    tr
      td <code>RouteDefinition</code>
      td.
        Defines how the router should navigate to a component based on a URL pattern.
    tr
      td <code>Route</code>
      td.
