title: Automatically switch to correct version of Node based on project
body: <p>Let's say I have 2 projects:</p>
  
  <pre><code>example1: requires node version 0.12.1
  example2: requires node version 0.10
  </code></pre>
  
  <p>Currently, when I <code>cd</code> into each project, I use <code>nvm use &lt;version&gt;</code> before running the application.</p>
  
  <p>Is there a way with node or nvm, to automatically switch to the needed version of node when I <code>cd</code> into each project?</p>
