JSON Editor based on XText

[angelozerr]

To display the data of teh MongoDB Document which is JSON, we need a JSON Editor.
It exists http://sourceforge.net/projects/eclipsejsonedit/ but not sure that it can be extended easily.

I think the clean mean was to use XText for this JSOn Editor. It exists this project https://github.com/oyse/jetson
but which seems dead. Study it and restart from scratch this project.
