MatrixPrediction: switch to DileptonMatrixMethod
compute_fake_factor: bugfix, accept TT and TL
fake.sh drop el stem (follows 279596d, amends f4d46b6)
update templates to DileptonMatrixMethod (follows d73b74b)
drop MatrixPrediction::getRFWeight obsolete
cleanup getFakeWeight
razor vars and passSrRazor*jet
passSrRazor0jet: tmp drop mDeltaR cut
fakeUtils: add razor stems
fake.sh: bugfix compute_scalefactors (no reg needed)
MeasureFakeRate2: add razor tuples (Sep_28 run)

Generate the ntuples needed to compute the compositions for Danny's
razor analysis. Temporarily disable all the other selections and
ntuples.
build_fake_matrices.py: add razor0j as valid region
razor0j, add mdr>20 (sugg by Anyes, run as Oct_16)
fake.sh add hint to create nutples
SusySelection::passSrRazor0jet: drop cl jet veto

trying to gain more stats for the fake composition in the razor selection
MeasureFakeRate2: don't write razor1j nutple

dropped ntjet req, so it is now useless
kin: add computeRazor
SusySelection::passSrRazor0jet: relax jet and pt criteria

trying to increase fake stats for compositions
MeasureFakeRate2: put back SsInc tuple
