all codes required to add GenLumiInfoProduct
all codes required to add GenLumiInfoProduct
make it possible to combine samples with different cross sections
force the uncertainty delta2Sig to be positive
add weights information in GenFilterInfo and compute errors following the formula that separates positive and negative weiths
remove ProcessLumi from LHERunInfo, use the same definitions of Process for lumiblock and run
add function that compute efficiency without separating positive and negative weights
separate cross section calculation based on whether hepidwtup number
add back the constructor that takes two unsigned integers as inputs
initialize the new datamembers of GenFilterInfo and insert back the line with classversion=10 to maintain backwards compatibility
update class_def.xml so that the new data members in GenFilterInfo are initialized with values of old data members. Replace all nFail variables with nTotalxxx
class_def.xml for GenFilterInfo: change to version=-10
change sumFailWeights, sumFailWeights2 to sumTotalWeights, sunTotalWeights2 in GenFilterInfo
