[Nexus] How to model a grating monochromator?

[Wellenreuther, Gerd]

Dear all,

I am right now trying to assemble the most important NeXus-building 
blocks for a virtual all-purpose SR-beamline 
(https://hdri-sdf.desy.de/index.php/SR_Example). I wonder how to 
properly represent a monochromator which is using gratings instead of 
crystals. What about introducing an NXgrating baseclass, and allow them 
to be used instead of NXcrystal in NXmonochromator?

And while we are thinking about this, what about multilayers? They are 
modeled using NXmirror, right? Could they be an option in 
NXmonochromator, too?

Cheers, Gerd
