simu user data

[SebGue]

Hello,

I am doing some optimization and had an idea for an improvement.
If you e.g. think of an optimization where you set magnet height and magnet width (by pole coverage from 0 to 1) and want to maintain the airgap, then you got design variable that are coupled somehow and could not be set with independent functions. (You got to e.g. iterate yoke diameters, magnet width in mm and so on.)
Therefore (to do no fancy tricks :-) ) an intermediate storeage somewhere in simu or machine would be great.
So do you mind if I introduce a property user_dict to Simu class for that purpose?

Best regards, Sebastian
