// Define a function named createList that takes one argument.
//   sites (object)
//
// The object has the following structure:
//    {
//      'TITLE': 'URL',
//      'TITLE': 'URL',
//      'TITLE': 'URL',
//      ...
//    }
//
// The function must return an <ul> element that contains <li> elements that
// each contain an <a> element. For example, given:
//    {
//      'Google': 'https://www.google.com',
//      'Facebook': 'https://www.facebook.com',
//      'GitHub': 'https://github.com',
//      'Galvanize': 'https://www.galvanize.com'
//    }
//
// It returns the following:
//    <ul>
//      <li><a href="https://www.google.com">Google</a></li>
//      <li><a href="https://www.facebook.com">Facebook</a></li>
//      <li><a href="https://github.com">GitHub</a></li>
//      <li><a href="https://www.galvanize.com">Galvanize</a></li>
//    </ul>
// 
// Clue: The function should use DOM methods/properties. You will be creating elements, setting attributes, and appending nodes. 
// Ie, use createElement(), textContent, setAttribute(), appendChild(),...
