' CLASS:  Quiz
'
' AUTHOR: Shawn McKenna
'
' DESC:   This is a java applet that is a simple Star Trek Quiz (TOS).  Currently at 10 
'	    questions.  After you enter the submit button, it goes to the corresponding HTML
'	    page.  Better results, better ending (I suppose).  Of course, there could be tons
'	    of changes for the better.
' 
' NOTE:   Server-side quizzes work better.  This program was written in a structured approach
'	    as opposed to a Object-Oriented approach.  The code is easily read and can be changed
'	    or added to quite effortlessly.
'
' GENERIC NOTE:	All my code has been tested, my apologies for any unforseen errors.  
'			Suggestions are always welcome.  Feel free to use or change any of this 
'			code.
'
' CONSTRUCTOR: NONE
'
' METHODS:
'	init()
'		MODIFIER: public
'     	DESC: Applet is initialized.                
'		RETURN TYPE: void	
'
'	action()
'		MODIFIER: public
'     	DESC: After submit button is pushed, action happens here.                
'		RETURN TYPE: boolean
'		NOTE: Depreacted method.  I just did this to actually have a program with this
'			method.  Use listeners instead.
'
'	goToPage(Integer intRight)
'		MODIFIER: public
'		DESC:	 This method is passed the number correct on the quiz and opens to the '			 corresponding (URL) web page.  Depending on the number right -- (better '			 score, better ending).
' 		RETURN TYPE: VOID 
'
' DATE MODIFIED:	 11/15/2000
' VERSION:		 1.4
'
' PREVIOUS VERSIONS:
'	Version 1.4 -- added more comments and changed more code.
'	Version 1.3 -- change source code. Still have to make endings for 2 or more right.
'	Version 1.2 -- I now have an ending for 1 right and I changed some code.
'	Version 1.1 -- I now have an ending for 0 right.
'	Version 1.0 -- I have not quite figured out what I should do with the results. So now the number right appear in the text '	box. Later, I might have something special like different endings according to points scored and maybe a list of the '	wrong answers. I am happier with my JavaScript quiz page. These quiz pages are best done in CGI, ASP or JavaScript. '	Java (AWT) seems to be a bit limited.
