CreateNF2FFBox
==============
```{function}  CreateNF2FFBox(CSX, name, start, stop, varargin)
```
Full definition:
```{code-block} matlab
function [CSX nf2ff] = CreateNF2FFBox(CSX, name, start, stop, varargin)
```

create the dump boxes needed for the near field to far field transformation

input:
- name:       name of this nf2ff box
- start/stop: start/stop coordinates for the nf2ff box (this box has to
              enclose all radiating structures!)
optional inputs:
- 'Directions': enable/disable specific directions, e.g.
                'Directions',[1 1 0 0 1 1]
                  -> disable nf2ff in +/-y direction
- 'Frequency': dump nf2ff in frequency domain, this will save disk-space
               but is less flexible, since only this frequencies can be
               used for the nf2ff calculations by CalcNF2FF
               See also AddDump for more information
- 'OptResolution': specify a dump resolution, this will save disk-space
                   See also AddDump for more information
                   e.g.: 'OptResolution', c0/max_freq/unit/15
