| /** What does a tree look like? ANTLR has a number of support classes |

| * |
| * NOTE: When constructing trees, ANTLR can build any kind of tree; it can |
| * even use Token objects as trees if you add a child list to your tokens. |
| * |
| * This is a tree node without any payload; just navigation and factory stuff. |
