+/* BMK_benchTimedFn() :
  * Similar to BMK_benchFunction(),
  * tries to find automatically `nbLoops`, so that each run lasts approximately 1 second.
  * Note : minimum `nbLoops` is 1, a run may last more than 1 second if benchFn is slow.
  * Most arguments are the same as BMK_benchFunction()
  * Usage - initialize a timedFnState, selecting a total nbSeconds allocated for _all_ benchmarks run
- *         call BMK_benchFunctionTimed() repetitively, collecting intermediate results (each run is supposed to last about 1 seconds)
- *         Check if time budget is spent using BMK_isCompleted_runOutcome()
