"""FEM module App init script

Gathering all the information to start FreeCAD.
This is the first one of three init scripts.
The third one runs when the gui is up.

The script is executed using exec().
This happens inside srd/Gui/FreeCADGuiInit.py
All imports made there are available here too.
Thus no need to import them here.
But the import code line is used anyway to get flake8 quired.
Since they are cached they will not be imported twice.
