Call mesh preprocessing during loading and before each time step
calculated
Do not cast mesh to tetr mesh when it's not necessary
Set rheology matrices for all local (includeing unused) nodes to prevent
problems with nodes in markered meshes
Create meshes outlines just after preprocessing done
Removed useless virtual qualifier
Make markered mesh movable
Removed dead code
Clease border cells map each times when processing mesh
Transfer both markered mesh and markered surface
