Store solver versions in BaseSolver

[ewu63]

Description of feature

There should be a way (via inheritance) to access and store the version of the inherited class instance. This can then be used in printing to make clear what version of the specific solver is.

Is this going to be redundant when Repostate is updated?

Hmm, this was aimed at a slightly different use case, i.e. accessing say CFDSolver.__version__ or something to fetch its version at run time. Then you can for example have different aeroOptions depending on the version if something was removed/added recently. But this is probably low priority, I don't see much use for this. I'd be okay with closing this if nobody is interested in this feature.

We can bring this up again and see if anyone is interested, your comment makes the scope more clear
