update history to a NamedTuple

history::Vector{Tuple{DateTime, Int, Function, T}}

What is the best format, downstream became a NamedTuple:

cc @Affie , do you think we should propagate the NamedTuple change upstream to here?

[dehann]

oh, also motivation why -- IIF is unable to use the debug function sandboxStateMachineStep without standardizing

[dehann]

also see IIF.repeatCSMStep!

[Affie]

The only problem I can see is the userdata field, IIF calls it csmc perhaps it can be changed to userdata or something more generic.

We can also just do something like this:

sandboxStateMachineStep(hist::Vector{<:NamedTuple}, step) = sandboxStateMachineStep(values.(hist), step)

I see IIF.repeatCSMStep! is basically a duplicate.

[Affie]

see #43 for an option.

It kind of works nicer in IIF since you can have custom printing and it doesn't crash vscode when writing out everything.
So we can add custom printing to FSM as well, but then it needs to be a NamedTuple to avoid type piracy.
