Introduce transform of Geometry.SettingOut.Level

#### Description:

As in the title, a type-specific transform for `Level` would be a nice feature. However, it will require extra checks for rigidness of transformation as well as no out-of-plane rotation. The first is solved with `IsRigidTransformation`, the latter should work (acc. to @IsakNaslundBh and me) based on T[3,3] == 1 check, in the standard matrix notation (`T[2,2] == 1` in the code).

@al-fisher @rolyhudson FYI, please shout if you disagree.
