Think about the "ops" handling

if ops is None:

Is it a good idea to have the ops decoupled from everything? Wouldn't it be better to have it connected to something, like maybe the simulation setup or the optimiser properties or something? Otherwise it is lying around somewhat on its own and is likely confusing to others.

Provide a convenient way to define basic optimisation setups. For example we could provide a further argument to the parameter class that determines if it is optimised or not. Then PROPTI can decide internally to sort the different parameters and users do not need to define different lists for parameter handling.
