changes:
- new field processing class producing frequency domain field-dumps
- Processing needs dualMesh and dualTime information
- fix in TD field dumps using always dual-Time

- This class is meant as an abstract base for any time-domain and rect-grid numerical solver.
- All processing methods should only use this base class

This is a new common class designed as an interface between an engine
and the processing routines which should become a part of common as well.
todo:
- migrate all processings to use this interface only
- lots of testing...

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...
the better approach is to create a new class (e.g. Dump)which contains all dump formats (currently vtk and hdf5). This class will then be responsible to choose a dump mode: in drawing units or in meters
This change modifies the behaviour of the complete program, if the SSE engine is used.
A better approach may be to only enable flush-to-zero in IterateTS()...
todo:
- more material parameters for the lorents model (currently only the plasma frequencies)
- code documentation
- examples & validation
- speed optimizations

The excitation variables and functions are separated into a class Excitation.
This allows completely different operator implementations (e.g. TLM) to use the excitations functions without deriving from class Operator.
- This class reads/writes combined CS- and FDTD-setup data and does the actual FDTD run.
- Examples now write there own xml file which is read by openEMS-class
- Standalone version possible with xml-file input
