JSON Lint EXT

Example for the Extended JSON parser: the editor uses the position information for marking JSON errors within the editor-view.
Enabling strict mode will give an error, if the JSON contains duplicate properties.
NOTE: The editor demo is based on the Esprima Demo using the JavaScript editor component of Orion.
