Operator:
- new method to setup the mesh: SetupCSXGrid()
- Most methods handling material and operator calculations are now protected.
- New method for accessing the material distribution.
Operator_Cylinder:
- overloaded SetupCSXGrid() handling cylindrical specialties
- This commit adds an additional line in alpha-direction
in case of a closed cylinder simulation. Thereby the material averaging
will be accurate at the alpha-interface

The cylindrical multigrid scheme needed a workaround:
An additional barrier is necessary to prevent a simultaneous MPI comm access.

this is a new multi grid approach for the cylindrical FDTD.
The FDTD domain will be split in two regions in radial direction.
The "inner" region will have half as many disc-lines in alpha direction and therefore allow for a much larger timestep which increases the simulation speed.
Todo:
- currently only a homogeneous disc is allowed in alpha direction
- some extensions have to be tested and prepared for this approach (e.g. pml)
- speed enhancement and more efficient memory usage
- lots and lots of testing...
