IterativeFakeCorrection: initial import
replace paths SusyPlotting -> SusyTest0

Details:
sed -i 's/SusyPlotting/SusyTest0/g' ../Root/*cxx ../SusyTest0/*h ../util/*cxx
SusyAna2012/SusyAnaDefs -> SusyTest0/SusyAnaDefsMatt
increase dbg lvl (trying to figure things out)
printout when we cannot find input histos
comment out isTrueDilepton
do not require isTrueDilepton if we are measuring the fakes
do not call selectAnaEvent (requires sig_lep); just require 2 baseline lep and m_ll>20
drop n_lep==2 requirement and relax m_ll>20 requirement

Details:
We cannot require exactly two leptons here, because most of the times
this is not the case in the control regions.
As a consequence, we can check that m_ll>20 only when there are
exactly two leptons, that is when the lepton pair is uniquely defined.
cannot check SS/OS when n_lep!=2
use latest inputs
add fileExists
remove the hardcoded filenames

Details:
- remove the hardcoded input/output file names.
- add the set* functions
- check and bail out when the inputs dont exist
- check and warn if the output exists
- Verified that the output is the same as before
do not iterate on invalid inputs
print file contents only when dbg
delete-trailing-space
allow to specify input/output on cmd-line

Details:
by default leave the files I'm currently using
initial import
SusyPlotting->SusyTest0 (now compiling)
