Freeze Vitruvius

[MartinLoeper]

Remove all dependencies to Vitruvius.
As Kiana and Dominik suggested, we copy over all required functionality into a special package.
The code inside this package will not be modified. This is necessary in order to easily replace or update it later on.

This will fix #50

We decided in our meeting today to:

• fork Vitruvius into KAMP organization and freeze a working version @layornos (hopefully accepted by him 😟 )
• include this freezed version in the team project set @MartinLoeper
• look into the new mwe syntax as suggested by Create a build with CI #43 @dwerle
