Detailed Description

Wrapper for MIComponentFactory supporting parallel model setup.

This MIComponentFactory provides parallelized model setup initiated by rank zero of the given communicator and makes those models available to be controlled by the root rank. This allows rank zero to set up SaplingProblem's through this factory exactly as if it was sequential; this class ensures that the other worker ranks perform the same SamplingProblem construction at the same time. In particular, parallel models are guaranteed to be set up in sync, so most external model codes should just work once the appropriate communicator is passed to them. Further, once SamplingProblem's are set up, worker processes listen for LogDensity requests from the respective ParallelAbstractSamplingProblem.
