#200 website: Use a class attribute for TOC

[Michael Schuerig]

Please enclose the entire navigation TOC in an element
with a class attribute such as "toc". The point is to identify
navigation elements that are only useful on a live
webpage, but aren't of any use in print. Thus, the TOC
could be excluded from print with a simple addition to the
used CSS stylesheet

@media print {
.toc {
display: none;
}
}

There already is a class="navtoc" used in the <p> containing
the toc. So I just added this style to example.css.
