title: Extracting values from JSON file using SuperObject
body: <p>As the title suggest I am trying to extract a value from a very simply structured JSON file using Delphi 7 and the SuperObject Library, but I have yet to find any examples that cover this most basic topic and was hoping some of the gurus here might be able to offer me some assistance.</p>
  
  <p>What I have is a simple JSON file (named test.json) that has the following structure and what I am wanting to know is how can I load this file in delphi and then extract the value for "last name" from the information provided. </p>
  
  <p>I am sure this is an extremely simple task, but as I stated before I was not able to find any examples on how to do this and was hoping for some help.  </p>
  
  <p><strong>example JSON file</strong></p>
  
  <pre><code>{
    id: 212,
    first_name: "bob",
    last_name: "smith",
    age: 25
  } 
  </code></pre>
