title: map two directive names to one directive
body: <p>I've got a directive which is set using a class because most of the properties are related to that class. </p>
  
  <p>The class is <code>resizable-sideways</code> or <code>resizable-updown</code>. </p>
  
  <p>Right now, the directive is called resizable, and I then look for the element class name of either <code>resizable-sideways</code> or <code>resizable-updown</code>. </p>
  
  <p>Is there some way to change</p>
  
  <p><code>
  angular.module('resizable',function()...
  </code></p>
  
  <p>and have it work with</p>
  
  <p><code>
  angular.module('resizable-sideways'||'resizable-updown',function()...
  </code></p>
