better mbo printer

[ja-thomas]

We want more information. Number of Focussearch points, number of focusations, parameters of lcb, ...

[jakobbossek]

I am going to add a printer for the infill criteria soon and call it in the printer for the control object.
This way we get information on the parameters of the criterion.

[jakobbossek]

Done for infill critrion in PR #286-
This will require ugly, longish code for the parameters of the infill optimizers.
IMHO we should do that after #200 is done.

[berndbischl]

we use simply focus search currently. that has 2 extra params.
hotfix this now, check whether we miss other really important params.

possibly add a note in #200
then close here
