[x3d-public] Geogebra 3d

[Andreas Plesch]

Geogebra is a cool geometry construction system designed mostly for
education which now also has a 3d version:

It can export Collada and STL currently. So adding X3D export may be
very doable. Here is the source for the Collada exporter:

https://dev.geogebra.org/trac/browser/trunk/geogebra/common/src/main/java/org/geogebra/common/geogebra3D/euclidian3D/printer3D/FormatCollada.java?rev=68519

The code is GPL licensed for non-commercial use, I think.
