Integrate Geogebra #2927
Description
GeoGebra is used by a number of maths teachers. There is a Moodle integration of GeoGebra, so it seems like a natural fit for us to integrate it as well
Describe the solution you'd like
GeoGebra is here: https://www.geogebra.org/?lang=en
The Moodle plugin is here: https://github.com/projectestac/moodle-mod_geogebra/blob/MOODLE_36_STABLE/locallib.php
It doesn't seem to be that much of a deal, but we should probably hold on that until after v2.0 of Chamilo to avoid duplication of work.
