title: JS/jQuery number increasing animation
body: <p>Let's say i have a div called <code>.number</code> containing a number.</p>
  
  <p>i want to increase that number to a new one dynamically with a counter increasing effect like this <a href="http://chartbeat.com/" rel="nofollow">one</a> in the bottom.</p>
  
  <p>Any lightweight solutions?</p>
  
  <p>Thanks</p>
