o RooHistPdf
- Moved from RooFit to RooFitCore because it is used by caching classes
o RooBCPGenDecay,RooBCPEffDecay,RooBMixDecay,RooNonCPEigenDecay
- Adapt to getCoefAnalyticalIntegral interface change in RooAbsAnaConvPdf
o RooBDecay
- Adapt to getCoefAnalyticalIntegral interface change in RooAbsAnaConvPdf
- Implement coefAnalyticalIntegral and getCoefAnalytical integral to forward
class to objects representing the coefficients
- Implement coefVars() so that RooAbsAnaConvPdf can sort out actual
dependents of each coefficient individually

o LICENSE
- Update copyright year
o RooGExpModel
- Fix analytical normalization of model w/o convolution: factor tau was missing
- Add function logErfC() with approximate of the log of the complementary error function
- Resolve numerical instability issues arising in several places from situations evaluation
exp(A)*erfc(B) where exp(A) because extremely large and erfc(B) because extremely small
by reparameterizing such terms as exp(A+logerfc(B)) when A becomes larger than 300.
Such issues mostly arise when small values of tau are chosen (<0.02).
[ Thanks to A. Chuvikov for reporting and suggesting the fix ]
- Resolve numerical instability issues arising when tau_decay and tau_gexp are identical
leading to problems in terms like (A+B)/C where A+B and C approach zero simultaneously.
The problem is solved by differentiating tau_decay and tau_gexp by epsilon in calculations
where the instability area is approached, or by neglecting such terms altogether when
they occur at values of x where abs(x)/tau > 200.
- Fix typo in advertiseAsymptoticIntegral() function name

o README
- Fix link to tutorial web page
o RooBCPGenDecay
- Rename _C and _S proxies to _avgC and _avgS
as Solaris compiler mysteriously crashes
on _C and _S as variable names
o RooGExpModel,RooGaussModel
- Add advertiseFlatScaleFactorIntegral() feature.
If active, model advertises an analytical integral
over the convolution variable _and_ the width scale factor
(typically dterr), and implements that as a flat integral.
(Good to ~1e-5 for most common applications of this model in BaBar)
Great improvement in speed results...
o RooPolynomial
- Implement dtor to fix memory leak

o All PDFs implementing analytical integration
- Follow hopefully final migration of getAnalyticalIntegral/
analyticalIntegral signature
o Roo2DKeysPdf
- Temporarily take out histogram writing as it doesn't compile
currently
o RooGaussModel
- Fix logic errors in evaluate() and analyticalIntegral()
which caused deferencing of non-existing parameters
in certain configurations.

o Roo2DKeysPdf
- Change RooDataSet::GetEntries() to RooDataSet::numEntries()
following reorganization of data set core code
o RooVoigtian
- Fix syntax error (default argument in ctor implementation)
o RooGExpModel
- Port of RFT RooGExpModel algorithm, including flip and higher
order options. Only the Exp x Gauss convolution
part is contained in this resolution model. The regular Gaussian
part added in the RFT version should be added using RooAddModel
