========================================================================
v00-00-81 /Sep04 (tulika):

No actual tagging code changes. New version was needed to be compatible
with p16.04.00. References to tmb_analyze were replaced by tmb_tree. Some
minor changes to remove warnings issued by the "picky" GCC compiler.

========================================================================
v00-00-80 /Apr04:

(1) Added four alternative algorithms for same-side tagging:

1  using highest Pt track (algorithm used so far; "preferred" by default)
2  using track with minimum delta-R w.r.t. B
3  using track giving minimum B+track mass
4  using track with minimum Pt w.r.t. (B+track) momentum
5  using track with maximum Plrel w.r.t (B+track) momentum

The user has access to answers from all five tagging algorithms; The
"preferred" algorithm answer is returned with "getSSTTag" method

(2) Enabled additional cuts for SST algorithm, change of default cuts for SLT
algorithm (details in doc/history_SST.txt, doc/history_SLT.txt)

(3) Updated input (d0root) files for one of the example macros

========================================================================
v00-00-70 /Jan04:

Code can now run in a mode where the user provides the taggers with data
(muons and tracks for now)

Structural changes: moved common code to new utility files
(TagUtil.cpp, hpp); fixes in matching between muon & tracks, data formats,
pointers to input files & proper initialization: part of TagUtil class

Bugfix in SST algorithm (details in doc/history_SST.txt)

========================================================================
v00-00-60 /Jan04: 

removed piece of code that rejected muons consistent with a J/Psi
decay from the list of tagging candidates (details in doc/history_SLT.txt)

========================================================================
v00-00-55 /Dec03:

removed muo_cand from code (mainly affecting SLT class; designed to
run on d0correct-ed TMBTrees)

changed muon quality definition for TMBTree format (details in
doc/history_SLT.txt) 

========================================================================
v00-00-50 / Dec03:
SST tagger: first implementation of tagging class

JetQ tagger: Changed default maximum dca cut: 10.0 cm --> 0.2 cm

public access methods: some renaming for better uniformity

small modifications to bin-size, fitting range in example macros

========================================================================
v00-00-41 / Nov03:
bugfix: "excluded" tracks were not excluded from OppJetQ class
========================================================================
v00-00-40 / Nov03: 

first implementation of OppJetQ tagging class

interface change: Btagger now accepts list of charged
tracks to be excluded from tagging (used to be list of muons); list
contains indices of branch  BF_TRACK (d0root-tuple) or fTrks
(TMBTrees)

updated macros to produce plots and keep statistics for different
taggers; modified cuts on J/Psi + K reconstruction to match those from
LP03; fixed error in calculation of tagging power uncertainty

bug fixes, improvements in SoftLepton class (details in doc/history_SLT.txt)
========================================================================
v00-00-32 /Oct03: 

Crashes when input chain contains more than one trees 
(input format: d0root-tuple); fixed by initiliazing pointers every
time a new tree is loaded in memory (no tagging code changes)
========================================================================
v00-00-31 /Sep03: 

tmb_analyze(?) header changes caused package not to compile; reordered
#include files, added std namespace to a few places (no tagging code changes)

========================================================================
v00-00-30 /Aug03: 

Updated code to be used with d0root ver 7.2 (now "quality" of d0root_btag and 
"nseg" of muon candidate are in sync; they used to be off by one unit in 7.1)

When looking for J/Psi --> mumu candidates in TMBTrees, will consider
muon pairs only if both muons have nseg>=0 (used to be "any nseg");
TMBTree code is now in agreement with d0root_btag code (making J/Psi's
by using nseg>=0 muons by default)

========================================================================
v00-00-20 /May03: 

first implementation of SoftLepton tagging & wrapper class
========================================================================
v00-00-10 /Feb03: 

"Moriond 2003" version of code (not in CVS)
