/*
Simpletext Java Applet.
Applet displays a text file from the web in a text area.
The Text Area is as large as the APPLET Width and Height commands.
There is no animation
It loads quickly
And provides information that can be provided quickly.
Utilizes the following Params
<PARAM NAME = "filename" Value = "URL">
<PARAM NAME = "fontname" Value = "Fontname">
<PARAM NAME = "fontsize" Value = "Fontsize">
This is very useful for placing on a page where you want to have information
added without having to touch the HTML in the page.  It can also be placed into
a table.
