The serialized form page (serialized-form.html) is currently very difficult to
navigate. Ideally, there should be a table of contents at the top, listing
all package names, grouped under headings such as:

    java.applet*
        java.applet

        java.awt.print

        java.beans.context

    org.w3c*
        org.w3c.dom
    org.xml*
        org.xml.sax

If the TOC cannot easily be placed at the top, at least place it at the bottom
with a link to it at the top like this:

   <a href="toc">Table of Contents</a>

(I say this because in the past Atul mentioned that the writer class
does not know the complete list of packages until it is done writing
out all the packages.)
