title: How to create a Graph from a text file
body: <p>I'm trying to create a Graph from a text file formatted (Vertex a) (Vertex b) (Edge between the two) but I'm stuck on how to take the names of vertex a and b and make those the names of the two vertices if that makes any sense. I know its got to be easy but I'm hitting a wall. I've tried things like:</p>
  
  <pre><code>Vertex s.next() = new Vertex();  
  </code></pre>
  
  <p>or saving the string into a variable and using it, </p>
  
  <pre><code>Vertex v1 = new Vertex();
  </code></pre>
  
  <p>I've looked around and cannot seem to find an example close enough to my issue to help me solve it.</p>
