 * Feel free to distribute and modify code, but keep reference to its creator
 *
 * Canvas Events class extends canvas object to help to attach mouse events 
 * to different shapes with minimal javascript code modifications.
 * Canvas context methods that perform actual drawing like
 * stroke, fill, strokeRect, fillRect, drawImage
 * return a shape object to which you can attach events
 *
