information needed getting timing information. Currently it return
the elapsed time for each calling processor..
A Epetra_Comm object is required for building all Epetra_Time objects.
Epetra_Time support both serial execution and (via MPI) parallel
distributed memory execution. It is meant to insulate the user from
the specifics of timing across a variety of platforms.
