Light Test for 2D distributed grid. Test chcek 9 process system by following test: 

1)Traversar writes to Boundary -- known BUG - this travarsar will write boundary condition in overlap too -- test is forcet to accept this
2)Traversar writes to Interior entities
3)Traversar writes to Allentities
4)Traversar writes its rank into AllEntities and then mesh si synchronized. Check Overlaping entities that data come from correct neibrouh
5)Traversar writes Linear function into AllEntities and then mesh is synchronized. All entities are checked that it has correc value.

Limitations:
Test run only on 9 process by code -> only regular 2D distribution of process is checked. Linear distribution is not chceked.
Test run only for double as RealType of DOF.
Only one size of global mesh is tested.
