title: Store Raphael papers in html object's id
body: <p>So I have some papers called "paper_0", "paper_1", etc. and I want to store them this way:</p>
  
  <pre><code>&lt;h2 id="paper_0" onclick="doThing(this.id, 'myFunction')"&gt;Name of this thing&lt;/h2&gt;
  </code></pre>
  
  <p>and in my javascript file:</p>
  
  <pre><code>//some code here
  function doThing(id, func){
     currentId = id; //store current game
     func(); //this would create paper_0 **error**
     //some code here
  }
  
  function removePaper(){
     currentId.remove(); // **error**
  }
  </code></pre>
  
  <p>so I have these 2 errors because <em>id</em> and <em>func</em> are both strings.</p>
  
  <p>Any suggestion how can I store the paper <strong>objects</strong>?
  Or can I give IDs to papers?</p>
