title: c++ libconfig and lists
body: <p>it seems I am unable to find any source telling me how to use lists with libconfig.</p>
  
  <p>Let's say my config file looks like this:</p>
  
  <pre><code>Layer1 = {
      Layer2 = {
          SomeOption = "MyValue";
          Options =  (
              {
                  Option = "Full Screen";
                  Value = "No";
              },
              {
                  Option = "Title";
                  Value = "Test";
              }
          );
      };
  };
  </code></pre>
  
  <p>How can I read Options with libconfig++ ? I can only find methods for reading single values.</p>
