LSETwigViewRenderer

Extends \ETwigViewRenderer

Twig view renderer, LimeSurvey overload

Allow to run sandbox Configuration Provide different render methods for different context:

render() : for general use
renderQuestion() : to render a question. It checks if a question template view should be use, else core's view (used from qanda helper).
convertTwigToHtml() : to render a string without any file (used from replacement helper)

The only tricky point here is the path problematic (where should be searched the views to render?)
