//  FairRun
//
//  class for the parameter versions of an event file
//
//  The name of each run is the run id converted to a string.
//  The run id number identifies the event file.
//  In the parameter ROOT file the valid parameter versions are
//  accessible via the name.
//  Associated with the run is a list of container
//  names with the versions of the containers in the two
//  possible inputs and the output (class FairParVersions).
//  The input versions are used during the initialisation
//  used during the initialisation of the containers.
