Adds a simple phpunit test

This adds a simple phpunit test for getting the name.
It's a good idea to have separate html files to test. Since this one has a lot of extraneous JS and other bits, might be better to replace it with something from Schema.org. This one should be good:

```
<div itemscope itemtype="http://schema.org/Person">
  <span itemprop="name">Jane Doe</span>
  <img src="janedoe.jpg" itemprop="image" />
  <span itemprop="jobTitle">Professor</span>
  <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
    <span itemprop="streetAddress">
      20341 Whitworth Institute
      405 N. Whitworth
    </span>
    <span itemprop="addressLocality">Seattle</span>,
    <span itemprop="addressRegion">WA</span>
    <span itemprop="postalCode">98052</span>
  </div>
  <span itemprop="telephone">(425) 123-4567</span>
  <a href="mailto:jane-doe@xyz.edu" itemprop="email">
    jane-doe@xyz.edu</a>
  Jane's home page:
  <a href="http://www.janedoe.com" itemprop="url">janedoe.com</a>
  Graduate students:
  <a href="http://www.xyz.edu/students/alicejones.html" itemprop="colleague">
    Alice Jones</a>
  <a href="http://www.xyz.edu/students/bobsmith.html" itemprop="colleague">
    Bob Smith</a>
</div>
