title: how to get value of stateparams in angular2?
body: <ol>
  <li>I am looking for stateparams in angular2. After searching on the angular2 official site i have found this. </li>
  </ol>
  
  <p><code>&lt;a [router-link]="[ '/MyCmp', {myParam: 'value' } ]"&gt;</code> </p>
  
  <p>but I can't understand how to get this value in the class or constructor of 
  the class?</p>
  
  <ol start="2">
  <li><p>In the angular cheatsheet there are three methods of route config is there any</p>
  
  <p><code>@RouteConfig([
    { path: '/:myParam', component: MyComponent, as: 'MyCmp' },
    { path: '/staticPath', component: ..., as: ...},
    { path: '/*wildCardParam', component: ..., as: ...}
  ])</code></p></li>
  </ol>
  
  <p>What is the difference between all these three: / and /: and /* ?</p>
