// think of it outside the context of the router, if you had pluggable
// portions of your `render`, you might do it like this
<App children={{main: <Users/>, sidebar: <UsersSidebar/>}}/>

// So with the router it looks like this:
const routes = (
  <Route component={App}>
    <Route path="groups" components={{main: Groups, sidebar: GroupsSidebar}}/>
    <Route path="users" components={{main: Users, sidebar: UsersSidebar}}>
      <Route path="users/:userId" component={Profile}/>
