Migrating ezgraphixdemo from HerokuGarden to Heroku

HerokuGarden is not longer supported, so I had to migrate the ezgraphix demo to Heroku, that process was really simple and elegant, the guys behind Heroku have done a great work, I still remember the first days of Heroku (when we needed a beta account), deployment and performance weren't as good as they are today, there is a big enhancement since these days and this will help people to easily deploy Rails apps, so keep up the good work!

So here's where you can find the new demo http://ezgraphixdemo.heroku.com/
