*) Replaced replaceHTML by a more versatile method (code by Kane). Please test for possible side effects if you use this method in any of your classes.

Browse Source 
*) Added a little bit of javadoc
*) Replaced tabs by spaces and beautyfied the code here and there.

The code is saved in UTF-8 encoding. I hope that does not cause any trouble.

* Lists are easy to do:
** start every line with a star
*** more stars means deeper levels
# Numbered lists are also good
## very organized
## easy to follow
; Definition list : list of definitions
; item : the item's definition
: A colon indents a line or paragraph.
A manual newline starts a new paragraph.

what we got in addition to that:
[= escape characters =]
<pre> preformatted text </pre>
what would be nice in addition to that:
nice to have:
