# Matrix element correction options
# By default matrix element corrections are switched off
# Note: In Herwig++ 2.7.1 matrix element corrections are switched on by default, however this is not recommend if LHE files are showered
# Requiring the hwpp_MECorr_Common block results that the user must make a choice
# Since the single blocks will be alphabetically ordered, we can override the common block and still require that it exists.
