Unused steering parameter

[dudarboh]

timingCut steering parameter is not used anywhere (as far as I can see...)

MarlinReco/CaloDigi/Realistic/src/RealisticCaloDigi.cc

Lines 79 to 83 in 39201c6

	// timing
	registerProcessorParameter("timingCut" ,
	"Use hit times" ,
	_time_apply ,
	(int)0);

However, in the ILD StandardProduction steering file is changed from the default 0 to 1.

If it is indeed not used, and it is just remnants it would be nice to clean it up completely to not cause any confusion what this 1 suppose to mean.
