Implemented the has_source value with mode setting.
Create iomodule.js

Use this file to add modules and to communicate with the web servers. The simulation's interface will be made up of individual modules (or IOModules). Modules are contained within html elements. For example, you can add a module contained within <div id="module"></div> by adding $('#module').ioModule('module', {}); to your javascript.
Update index.html

Changed index.html so that it uses iomodule.js
