move all vector/matrix instantiation to constructor
further optimization of multifit
improve printout in GenXSecAnalyzer and add to default filter summary sequence
don't exclude resonance decay products from gen jets, since this cannot in fact be done in a robust and generator-agnostic way
add missing dictionary for GenLumiInfoProduct data member
skip cross-section calculation if GenLumiInfo is not available (eg for single particle gun)
more fengshui
as much as I can do so far, sadly only 10%
review all use of views (changes are in the noise for timing)
threading improvements
move from cout to LogPrint
remove -g
add (and enable) option to override SPINUP in lhe file for Pythia8 tau decays
fix up exception as requested
