An archive for storing local or parallel data wrapping BinaryFstreamInputArchive.
Reads of process local objects loads the value originally stored by process zero which is then broadcast to all processes.
Reads of parallel containers (presently only WorldContainer) load all data.
The number of IO nodes or readers is presently ignored. It is forced to be the same as the original number of writers and therefore you cannot presently read an archive from a parallel job with fewer total processes than the number of writers.
