possibility to convert any dom element to glyph
Usage:
<h2 class="glyphus">Foo bar baz</h2>
<p class="glyphus">Foo bar baz</p>
<ul class="glyphus">
<li>Foo bar baz</li>
<li>Foo bar baz</li>
</ul>
Glyphus must iterate on the dom to search all element with a class glyphus
and convert them into glyphs.
