[Feature request] - Refactor of the Nuclide/Zaid objects #183
Description
Is your feature request related to a problem? Please describe.
After the introduction of the irradiation module, a new object Nuclide has been added to F4Enix which may have some overlap with the Zaid object of the materials module and of the FispactZaid of the fispact_legacy_out module.
Describe the solution you'd like
It would be nicer to have a single Nuclide/Zaid object can be used in different contexts. This would not be a complex operation per se, but it would require some heavy refactoring and possibly a break of compatibility with older releases depending on implementation.
