  PWGLF/FORWARD/analysis2/AliFMDCorrector.cxx
  PWGLF/FORWARD/analysis2/AliFMDMCCorrector.cxx
	Updates to use new OADB structure and updated corrections
  	manager (see more below)

- PWGLF/FORWARD/analysis2/corrs/ForwardOADBGui.C
  PWGLF/FORWARD/analysis2/corrs/MigrateOADB.C
  PWGLF/FORWARD/analysis2/AliOADBForward.h
  PWGLF/FORWARD/analysis2/AliOADBForward.cxx
	Migration of PWGLF/PWGLF/FORWARD/corrections to
        OADB/PWGLF/FORWARD/CORRECTIONS.  Corrections are now stored in
  	a TTree (one tree per correction) and indexed using the run
  	number, collision system, center of mass energy, L3 field, and
  	simulation and satellite flag.  The class AliOADBForward
  	provides an interface to that structure for both reading and
	writing.

- PWGLF/FORWARD/analysis2/AliCorrectionManagerBase.h
  PWGLF/FORWARD/analysis2/AliCorrectionManagerBase.cxx
  PWGLF/FORWARD/analysis2/AliCentralCorrectionManager.cxx
  PWGLF/FORWARD/analysis2/AliCentralCorrectionManager.h
  PWGLF/FORWARD/analysis2/AliForwardCorrectionManager.h
  PWGLF/FORWARD/analysis2/AliForwardCorrectionManager.cxx
  	New base class for correction managers.  Uses the new OADB
  	structure. The central corrections are new handled by separate
  	singleton rather than embedded class, to make the code more
  	stream-lined.  Correction managers register possible
  	corrections using services of the base class, and then reads
  	in the requested corrections based on the run number,
  	collision system, center of mass energy, L3 field, and
  	simulation and satellite flags. Each registered correction
  	decides how to be addressed, and the base class ensures this
  	addressing

- PWGLF/FORWARD/analysis2/AddTaskCentralMult.C
  PWGLF/FORWARD/analysis2/AddTaskForwardMult.C
	Fixes for new OADB structure and correction managers.  Note,
	we should hardly ever force a correction set now, since we can
	load based on the run number.  Still useful for tests, so
	won't remove it just yet

- PWGLF/FORWARD/analysis2/tests/RingBits.C
  PWGLF/FORWARD/analysis2/tests/TestFCM.C
	Some new tests

- PWGLF/FORWARD/analysis2/AliCentralMultiplicityTask.h
  PWGLF/FORWARD/analysis2/AliCentralMultiplicityTask.cxx
  PWGLF/FORWARD/analysis2/AliCentralMCMultiplicityTask.h
  PWGLF/FORWARD/analysis2/AliCentralMCMultiplicityTask.cxx
	Use new singleton correction manager.  Add flag to turn on
  	additional diagnostics.

- PWGLF/FORWARD/analysis2/AliForwardMultiplicityBase.h
  PWGLF/FORWARD/analysis2/AliForwardMultiplicityBase.cxx
  PWGLF/FORWARD/analysis2/AliForwardMultiplicityTask.h
  PWGLF/FORWARD/analysis2/AliForwardMultiplicityTask.cxx
  PWGLF/FORWARD/analysis2/AliForwardMCMultiplicityTask.h
  PWGLF/FORWARD/analysis2/AliForwardMCMultiplicityTask.cxx
	Moved a lot of functionality into base class.  Cleaned up
  	additional diagnostics introduced by Marek - duplicate and
  	broke structure of the code.  When loading the energy loss
  	fits, make sure we cache where to find the good fits.  Added
  	option to store one histogram per ring per event on the output
  	AOD tree.

- PWGLF/FORWARD/analysis2/AliBasedNdetaTask.cxx
	Code clean-up, and remove some stuff introduced by Marek which
	breaks the code

- PWGLF/FORWARD/analysis2/gridAnalysis.sh
  	General fixes and fixes for new OADB correction storage.

- PWGLF/FORWARD/analysis2/AliForwardMCCorrectionsTask.cxx
  PWGLF/FORWARD/analysis2/AliCentralMCCorrectionsTask.h
  PWGLF/FORWARD/analysis2/AliPoissonCalculator.cxx
  	Some clean-up

- PWGLF/FORWARD/analysis2/AliFMDMultCuts.cxx
  	Minor fixes

- PWGLF/FORWARD/analysis2/AliAODForwardMult.h
  PWGLF/FORWARD/analysis2/AliAODForwardMult.cxx
  	Add satellite information

- PWGLF/FORWARD/analysis2/AliForwardUtil.h
  PWGLF/FORWARD/analysis2/AliForwardUtil.cxx
  	Set more realistic upper limits on sigma in Delta fits -
	crucial, or too many fits will fail.  Added member function to
	re-initialize bins of a histogram.

- PWGLF/FORWARD/analysis2/AliForwardQATask.h
  PWGLF/FORWARD/analysis2/AliForwardQATask.cxx
  	Fix for satellite usage.  Cache valid bins from Delta fits.

- PWGLF/FORWARD/analysis2/AliFMDEnergyFitter.cxx
  PWGLF/FORWARD/analysis2/AliFMDEnergyFitterTask.h
  PWGLF/FORWARD/analysis2/AliFMDEnergyFitterTask.cxx
	Task does not load correction manager (not needed).  Better
  	peak finding.

- PWGLF/FORWARD/analysis2/AliDisplacedVertexSelection.h
  PWGLF/FORWARD/analysis2/AliDisplacedVertexSelection.cxx
	Added some diagnostics

- PWGLF/FORWARD/analysis2/AliFMDCorrAcceptance.h
  PWGLF/FORWARD/analysis2/AliFMDCorrAcceptance.cxx
	Code to draw correction.  Disabled.  moved to CorrDrawer.C

- PWGLF/FORWARD/analysis2/AliFMDCorrELossFit.h
  PWGLF/FORWARD/analysis2/AliFMDCorrELossFit.cxx
	Updates to drawing code.  Also added caching of good bins.

- PWGLF/FORWARD/analysis2/AliFMDEventInspector.h
  PWGLF/FORWARD/analysis2/AliFMDEventInspector.cxx
  PWGLF/FORWARD/analysis2/AliFMDMCEventInspector.h
  PWGLF/FORWARD/analysis2/AliFMDMCEventInspector.cxx
	Fixed coding conventions. Added cache of run number.  Added
  	additional diagnostics histograms.  Satellite analysis is not
	diagonal to normal - will flag output as satellite instead.

- PWGLF/FORWARD/analysis2/AliFMDSharingFilter.h
  PWGLF/FORWARD/analysis2/AliFMDSharingFilter.cxx
  PWGLF/FORWARD/analysis2/AliFMDMCSharingFilter.h
  PWGLF/FORWARD/analysis2/AliFMDMCSharingFilter.cxx
	Removed non-simple merging method (not used).  Removed useless
        diagnostics histograms.  Added option to consider kInvalidMult
        signals as zero (0) signals.  This is needed for data
   	reconstructed with AliROOT prior to v4-19-Rev-09.  Before that
	revision, zero-signal strips are flagged as kInvalidMult.
   	This was introduced by someone who (wrongly) tried to optimize
	storage.  See also comments in ForwardAODConfig.C.  Expanded
	ELoss histograms to record number of kInvalidMult.

- PWGLF/FORWARD/analysis2/AliFMDDensityCalculator.cxx
  PWGLF/FORWARD/analysis2/AliFMDDensityCalculator.h
  	Added flag for minimum quality of fits (should be no less then
	8). Removed some useless diagnostics histograms.

- PWGLF/FORWARD/analysis2/AliFMDHistCollector.h
  PWGLF/FORWARD/analysis2/AliFMDHistCollector.cxx
  	Introduced new embedded class for vertex bin information.
	Added option to create summed per-vertex, per-ring histograms
	of dN/deta.  Note, this can be misused to create a 1-step
	analysis of the forward data and should be avoided.  Also add
	possibility to create a set of 3D histograms of summed
	per-centrality, per-ring histograms.  This, again should be
	avoided.

- PWGLF/FORWARD/trains/ParUtilities.C
  PWGLF/FORWARD/trains/TestAuxPAR.C
	Add possibility to build PAR of auxiliary files

- PWGLF/FORWARD/trains/Helper.C
	Do not always rebuild

- PWGLF/FORWARD/trains/ProofHelper.C
	Implement some missing -Weffc++ functions.  Add possibility to
	build PAR of auxiliary files

- PWGLF/FORWARD/trains/GridHelper.C
  PWGLF/FORWARD/trains/GridTerminate.C
	Allow more flexible spec of TTL
	(<days>d<hours>h<minutes>m<seconds>s), and AcLic the Terminate
	macro.  Also make it possible to do the final merge and
  	terminate on the client (local) machine.

- PWGLF/FORWARD/trains/GridWatch.C
  	Refresh token every 6th hour, and fix up batch mode

- PWGLF/FORWARD/trains/AvailableSoftware.C
	Allow extra flags for automatic selection to only take
	releases, analysis tags, or any of the two.

- PWGLF/FORWARD/trains/TrainSetup.C
	Documentation comments and do not always rebuild

- OADB/PWGLF/FORWARD/CORRECTIONS/data/fmd_corrections.root
  OADB/PWGLF/FORWARD/CORRECTIONS/data/spd_corrections.root
	Added databases used by PWGLF/FORWARD analysis.
