title: lodash multi-column sortBy
body: <p>There's a nifty method to sort an array of objects based on several properties:</p>
  
  <pre><code>var data = _.sortBy(array_of_objects, ['type', 'name']);</code></pre>
  
  <p>However that is only for ascending sorting. Is there some handy way of defining direction per column? E.g.</p>
  
  <pre><code>var data = _.sortBy(array_of_objects, [{'type': 'asc'}, {'name': 'desc'}]);</code></pre>
