Description
Summary:
add divergences, treedepth exceedence, and energy diagnostics as discussed in Mike's case study http://mc-stan.org/users/documentation/case-studies/rstan_workflow.html to the printed output by summary(fit), where fit is a fit object from rstanarm
Description:
ShinyStan can be used to show all these diagnostics, but when making R notebooks it's nice to be able to get diagnostics summary also non-interactively. Mike's diagnostic utilities don't work for rstanarm fit objects. I think it would be good to show in summary(fit) by default also 0 divergences, 0 treedepth execeedence, passing the energy test.

Research direction
Start by locating the summary(fit) method for rstanarm fit objects and read the linked case study's diagnostic requirements. Compare the available fit diagnostics with the requested divergences, treedepth exceedances, and energy test, then verify that summary(fit) reports them non-interactively by default.
