Description

The plugin could be kind of nasty depending on how familiar you are with
programming.  The more of a programmer you are, the more nasty it might
look so I apologize since my background is not in programming and I only
do so on a need-be basis.   

This is not a step by step guide on how to implement the plugin, but a
guide to the files and execution procedure.  All the file included are
RTF files so they can just be opened, but will need to rename them
accordingly.  If you have questions, please let me know.
