There is shor test of this stuff for 1D 2D and 3D.

Relpaced tabs with 4spaces.

* parallel-reduction:
  Fixed ArrayOperations::compareMemory for MIC
  Fixed parallel reduction for MIC
  General parallel reduction on host
  Refactoring parallel reduction operations

- used variadic templates to avoid code bloat
- added execHost static method to avoid nvcc warnings

- separate data types for input arrays of binary operations
  (necessary for the equality comparison of two arrays of different
  type)
- added separate template parameter for ResultType, which defaults to
  the RealType
  (the goal is to allow sum of bool vectors into int instead of bool)

Improve of DistributedGrid: Distributed grid teak overlap size as parameter.

- Add Template abstraction to MPIIsend and MPIIRecv
- Distributed Grid Synchronizer is now indipendend on DOF datatype (bound to basic C types, types known by MPI)
- Distributed Grid Synchronizer now uses WaitAll function.

Test 3Ddistribuovaného gridu. Chybí test sousedů, je limitován na 27 procesorů, netestuje 1D či 2D distribuci nodů.

Lihgt refactorization of 1D and 2D distributedGridSynchronizer. Now hav same interface as 3D distributedGridSynchronizer and function Synchronize is lighter.

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.

Working implementation of 3D distributed grid, but 3D traversars do not know about distributed grid, Process{Boundary/Interrior}Entities do not work correctly with distributed gird.

Partial implementation of 3D distributed grid. není funkční, potřebuju rychledostat rozpracovanou práci ze servrovny, kde nejde klima.
