QCD.cpp now reads lifetime of the meson with the Meson::setLifetime() method. Width is no longer an argument of Meson(). Width of the meson can be now accessed through Meson::computeWidth() and the lifetime trough Meson::getLifetime. Default value of lifetime for meson set to > age of the universe.
Changes cascaded from Width -> Lifetime in Meson.cpp echoed.
IMPORTANT: MODEL PARAMETERS IN CONF FILE UPDATED. PLEASE UPDATE YOU CONF FILES. All references to Meson widths changed to lifetimes.
