Update of /cvsroot/htmlparser/htmlparser/src/org/htmlparser In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv5117/htmlparser/src/org/htmlparser Modified Files: Node.java Parser.java PrototypicalNodeFactory.java Log Message: Documentation revamp part three. Reworked some JavaDoc descriptions. Added "HTML Parser for dummies" introductory text. Removed checkstyle.jar and fit.jar (and it's cruft).
