Raphael animation easing plugin

Derived from jQuery Easing Plugin (version 1.3): http://gsgd.co.uk/sandbox/jquery/easing/

View a demo of animation easing techniques here: http://demos.daylife.com/samuel/svg_photo_flipper_prototype.xhtml

NOTE: As of June 2009, this plugin requires a forked version of RaphaelJS. You can download it here: https://github.com/conesus/raphael/tree. Hopefully, these forked changes will be merged with the master Raphael JS code.

To use:

1. Include the raphael.easing.1.3.js file after your raphael.js file.
2. Specify the easing technique in the .animate() function, like so:

`Element.animate({'scale': [1.25, 1.25]}, 750, 'easeOutCubic', callback);`
