This library requires jQuery and RaphaelJS to work.
You can find these at: jquery.com and raphaeljs.com respectively.

--------INSTALLATION--------
Include jQuery, RaphaelJS and JRPad in the head of an html document.

Example:

	<SCRIPT LANGUAGE="JavaScript" type="text/javascript" SRC="jQuery.js"></SCRIPT>
	<SCRIPT LANGUAGE="JavaScript" type="text/javascript" SRC="raphael.js"></SCRIPT>
	<SCRIPT LANGUAGE="JavaScript" type="text/javascript" SRC="JRPad.js"></SCRIPT>
	
--------USAGE--------

It's probably a good idea to be fairly familiar with jQuery before using JRPad: http://docs.jquery.com/Main_Page

-Put all JRPad calls inside of a jQuery $(document).ready function.
-You must pass the id of the div element you want the JRPad to be in to JRPad's constructor:
						var newPad = new JRPad("drawingArea");
						(note that the "#" symbol before the id is not needed)
						
-And have a div like:
						<div id="drawingArea" style="width:200px; height:400px;"></div>
						(JRPad will size itself to to 200 by 400 pixels automatically)
						
-Here's the messy part. Include this code (Assuming your div is named "drawingArea". You can of course call it whatever you want.):
						$("#drawingArea").mousedown( function(e)
						{
							newPad.setMouseDown(true);
							newPad.drawDot(e);
							return false;
						}).mouseup( function()
						{
							newPad.setMouseDown(false);
						});

						$("#drawingArea").mousemove( function(e)
						{
							panewPad.drawLine(e);
						});
						
-Other functions available:
						.eraser(); //changes the stroke color to the same color as the background. Call it in a jQuery click event for best results.
						.setColor(colorValue) //can take html color names ("red", "green", "black") or hex color values ("#000000", "#3f2a5e").
						.setWidth(widthValue) //pass an int or a decimal to it to change the width (thickness, size, whatever) of the "brush".
