Consider using ModelParameters.jl for parameters

See rafaqz/ModelParameters.jl#8 (comment) for reference.

Maybe try by building a small example AIBECS model manually and go from there.

Another thing that is sometimes a pain with the current struct implementation is its rigidity. You can't change the parameters' struct on the fly. Maybe a simpler wrapped array type would be better, and more in line with SciML or something like ModelParameters.jl

Additional note: an important feature would be the ability to read and write csv files.
