Non uniform Pt Binning now added to the ZK's An prediction plot vs W-Pt Gen and W-Pt Reco
W_Asymmetry macro plots the An asymmetries for W+, W- and Z0 with the correct labelling and includes the Syst. errors in the error bars.
Furthermore plots the value of relative syst. errors in each bin on the bottom of the plot.
cosmetics: lines added to hWBosonPz_GoodRecoFraction histogram
Asymmetries versus rapidity and eta are now calculated only for W-Pt < 7 GeV
updated labels
