S3UI Framework

S3XRC being a powerful backend that serves XML and JSON in a RESTful manner has now got a front-end framework that can exploit its positives. S3UI - the new ExtJS based front-end help us not only utilize S3XRC but also save a lot of bandwidth by exchanging information in JSON instead of full page reloads. This in turn aims to create an easy and quick workflow for different tasks that a user does with Sahana Eden.
