Exports geometry to a *geo* file and all materials to *mat* files.

:arg outputdir: full path to a directory where the files will be saved.
Note that any conflicting files will be overwritten without warnings.
:return: a :class:`tuple` and a list of :class:`tuple`.
The class:`tuple` contains 2 items: the :class:`PenelopeGeometry`
object used to create the *geo* file and the full path of this
*geo* file.
Each :class:`tuple` in the list contains 2 items: the
:class:`PenelopeMaterial` object and its associated *mat* filepath.
The order of the materials is the same as they appear in the
geometry file.
In other words, the first material has an index of 1 in the
geometry file.
