// FamilyTree Example
// Class Main

// Hard code this family tree:
//
//          +-----------John---------------+
//          |             |                |
//       Arthur        Marjorie          Randolf
//        /  \          /   \              |
//       /    \        /     \             |
//   Jason   Katie   Barry Jennifer      Chloe
//     |
//   Walter
//
// Then print out in depth first order using toString.
