title: Require library inside mongo shell
body: <p>Is it possible to require a library in mongo shell? I need to run some code (update my documents) and for that I need a specific library. In example:</p>
  
  <pre><code>require("library")
  ...Some code
  MyTable.update()
  </code></pre>
  
  <p>I know that I could run inside node.js, so I am looking for the mongo shell solution.</p>
