Reverted back to the original behavior for the extra lepton vetoes until we
figure out how we want to do them. Also added anti-isolated versions of the
|d0| < 50 micron and |d0| < 100 micron preselections.
Added the missing hits cut to the conversion rejection and added versions of
the preselection with |d0| < 100 micron and |d0| < 50 micron cuts.
Fixed the ECAL crack veto so that it uses "isEBEEGap" instead of the electron
pseudorapidity.
Converted rstrip to re.sub.
Added same-sign versions of each of the three signal regions.
