> refactor bsp() in allowing checkpointed messages to be recovered.
> ChiaHung Lin had a fancy idea in chaining superstep class to make the whole
> recovering more convenient and less error prone, or at least possible.
> A user does not define a BSP anymore, instead he defines a single superstep
> inside of a computation class. A user is able to chain these in a specific
> ordering. After each of this computation the framework calls sync() and
> exchanges the messages.
