/**
* JSDocument manages a single JavaScript source document
*
* __EDITING__
*
* Editing the document will cause the script to be reloaded via the
* ScriptAgent, which updates the implementation of all functions without
* loosing any state. To support redrawing canvases, jQuery must be loaded
* and a rerender method must be attached to every canvas that clears and
* renders the canvas.
*
* __HIGHLIGHTING__
*
* JSDocument supports highlighting nodes from the HighlightAgent. Support
* for highlighting the nodes that were created / touched by the current
* line is missing.
