Bugfixes

Bug in statistical inefficiency computation where self.max_n_iterations wasn't being used was fixed (#577).
Bug in estimated performance in realtime yaml file fixed by iterating through all MCMC moves (#578)
Potential bug fixed by explicitly updating and broadcasting thermodynamic states in replicas, when used in an MPI (distributed) context.
Issue #579 (#587).
Bug in handling unsampled states in realtime/offline analysis fixed by using MultiStateSampler._unsampled_states to build the mbar estimate array.
Issue #592 (#593)

Enhancements

DHFR test system does not require parmed as dependency, since OpenMM can now handle prmtop/inpcrd files.
Issue #539 (#588).
MultiStateSamplerAnalyzer now allows to manually specify n_equilibrium_iterations and statistical_inefficiency parameters. (#586).
