/**
 * TOC.js: create a table of contents for a document.
 *
 * This module defines a single maketoc() function and registers an onload
 * event handler so the function is automatically run when the document
 * finishes loading.  When it runs, maketoc() first looks for a document
 * element with an id of "toc". If there is no such element, maketoc() does
 * nothing.  If there is such an element, maketoc() traverses the document
 * to find all <h1> through <h6> tags and creates a table of contents, which
 * it appends to the "toc" element.  maketoc() adds section numbers
 * to each section heading and inserts a link back to the table of contents
 * before each heading.  maketoc() generates links and anchors with names that
 * begin with "TOC", so you should avoid this prefix in your own HTML.
 *
 * The entries in the generated TOC can be styled with CSS.  All entries have
 * a class "TOCEntry".  Entries also have a class that corresponds to the level
 * of the section heading.  <h1> tags generate entries of class "TOCLevel1",
 * <h2> tags generate entries of class "TOCLevel2", and so on.  Section numbers
 * inserted into headings have class "TOCSectNum" and the generated links back
 * to the TOC have class "TOCBackLink".
 *
 * By default, the generated links back to the TOC read "Contents".
 * Override this default (for internationalization, e.g.) by setting
 * the maketoc.backlinkText property to the desired text.
