title: How do I split out parameters from a url in Iron Router?
body: <p>I have a Meteor web app. and I have URL's formatted like this:</p>
  
  <p><code>/box/bx_0/12345/bx_1/67890/</code> ...etc...</p>
  
  <p>I want to be able to extract the pairs like this into an array in my Router file:</p>
  
  <pre><code>boxes['bx_0'] = 12345;
  boxes['bx_1'] = 67890;
  </code></pre>
