Timers_init(real(OUT) :: initialWCTime)
Initialize the timer data structures. This will essentially delete all information previously gathered by all timers and make it safe to start timers from scratch. In the middle of a run, for instance, this could be called once per timestep along with Timers_getSummary to get timer summary information for each timestep.
initialWCTime -- the initial wall clock time when this was called.
