Fuse all parameter types?

[AtiyahElsheikh]

Can work parameters (within the type WorkPars) be viewed as Demography parameters?

The question whether an internal architecture distinguishing demography from other elements (e.g. economy) is needed. If no, then Demography module does not look to be needed / distinguished. However, my intuition is that, indeed, economic parameters need to be placed within their own sub-modules. This would be useful in many situations, for instance, executing purely demographic simulations (without economic elements).

It might be easier to simply fuse all parameter types a model uses into one (using e.g. CompositeStruct).
