Introducing a JSON interface to Airavata Client side and Registry component

by Shameera Rathnayaka for Apache Software Foundation

Apache Airavata uses XML as its data format. However with the proposed web based graphical client UI in the Airavata GSoC 2013 master project, it is always good to have an interface to work with JSON data format.To do this we will introduce a standard way to convert JSON messages to XML before handing over to back end componentst and convert XML messages to JSON messages before sending it to Registry and web client UI.
