Added storage of Z shape parameters (values are now used directly, so the shape for MC comes from MC, shape for MCwithS comes from MCwithS, and shape for data comes from data); added check that edge cache is valid and not opened simultaneously; adapted cut for Z line shape to avoid any interference between sstream and tcut version; added option to avoid storing all correlation plots; added marker to -log(L) plot to show accepted minimum
Added new functionality to RooHist: a ratio histogram
