Added "Preselection_NoTrigger". Pretty much explains itself.
Added a "-i" option for the number of points proposed to fill a single Markov
chain. Also changed the default value of "-r" to match the default number of
tries of combine (10).
Modified fetchLimits so that it will automatically plot the "optimized" limit,
based on the best expected limit, when multiple source directories are given.
For graphs, "source" is now a list. If multiple sources are defined, then the
"optimized" limit will be plotted, based on the best expected limit from the
sources.
