Transitioning from pystan 2.x to 3.x

@Garren_Hermanus

When you say you recommend using cmdstanpy is this only for extracting the metric or is it for drawing additional samples from an already tuned fit? I.e. using the metric and stepsize, with some init (probably sample means) from the fit as fixed parameters?

there is a nice summary of the differences here: CmdStanPy 1.0 - #3 by WardBrian
