Description: Currently only functions to enhance plain text with HTML tags.
<p>
Wrapper class for various parsing routines, that convert plain text to HTML.
They try to recognize cites, URLs, plain text formattting like *bold* etc.
See <http://www.bucksch.org/1/projects/mozilla/16507/> for a description.
