 * Frames are represented as a tree structure. eg:
 *
 *            index.html
 *                |
 *      --------------------
 *     |                   |
 *   nav.html          main.html
 *                         |
 *                --------------------
 *               |         |         |
 *            top.html  mid.html  end.html
 *
 * might represent something like:
 *
 *   ------------------------
 *  | nav.html |  top.html  |
 *  |          |------------|
 *  |          |  mid.html  |
 *  |          |------------|
 *  |          |  end.html  |
 *  -------------------------
 *
 * where the left frame is main.html with three sub frames (top, mid, end)
 * and the entire page is index.html with two sub frames (nav, main)
 *
 * This is hung off the browser window structure.
