Neutron instrument settings for analysis

[MBartkowiakSTFC]

In the long run MDANSE should include a database of neutron scattering instruments, which can be used for selecting analysis parameters.

The intention is to enable realistic calculation of neutron experiment results. By selecting a specific instrument, the user should be able to impose the corresponding resolution, q range and energy range on the analysis results.

This work will likely be connected to a more general project of creating a library for handling instrument definitions that can be used by other software packages as well.
