Subject: svtools: HtmlWriter - for writing HTML structure to a stream

HtmlWriter is used to write the structure of a HTML document to
a stream. The goal is to abstract the messy construction of
strings when writing attributes of a html element and other
HTML specifics needed when structuring a HTML document.
