title: How do you get the params on a Route Handler with React Router
body: <p>I am trying to redirect a route to another route, and pass some params, like so:</p>
  
  <pre><code>var UnAuthenticatedClass = React.creatClass({
    statics: {
      willTransitionTo: function (transition) {
        if(!isLoggedIn()) {
          transition.redirect('signin', {
            originalTransition: transition
          });
      }
    }
  ...
  </code></pre>
  
  <p>My signin route:</p>
  
  <pre><code>var SignIn = React.createClass({
    componentDidMount: function() {
      console.log(this.getParams().originalTransition); // returns undefined
    },
  ...
  </code></pre>
  
  <p>No matter what I put in as params, this.getParams() returns an empty object. Any suggestions?</p>
