title: Unity IoC container name and resolution
body: <p>Are these statements equivalent (Am I getting the same object)?</p>
  
  <pre><code>unity.Resolve&lt;ITest&gt;();
  </code></pre>
  
  <p>and </p>
  
  <pre><code>unity.Resolve&lt;ITest&gt;(name : null);
  </code></pre>
  
  <p>If not what is the default name when I register without passing in the name parameter?</p>
  
  <p>Eg. when I do this:</p>
  
  <pre><code>unity.RegisterType&lt;ITest,Test&gt;();
  </code></pre>
