o RooProdPdf

    - Fix a handful of small memory leaks


  o RooDataHist

    - When importing data from TH1s with non-uniform binning, import by default the density
      and not the absolute value.

    - Add option to Import() to import absolute value instead of density (useful for histograms
      with ratio-based contents such as efficiencies)


  o RooAddPdf

    - Bug fix in analystical coefficient integration


  o RooAbsTestStatistic

    - Introduce clearer error message when dataset for simultaneous fit 
      cannot be split due to absence of index categgory


  o RooMCStudy

    - Improve info messages


  o RooSimWSTool

    - Add handling for splits in non-lvalue category functions such as RooMappedCategory


  o RooMinuit,RooMinimizer

    - Change contour() code so that it restores function parameters at original values at end of call


  o RooGlobalFunc

    - Add optional boolean argument to Import() to support change in RooDataHist


  o RooRandomizeParamMCSModule

    - Fix smal memory leak


  o RooHistPdf

    - Fix bug in (partial) analytical integrals for cases where underlying histogram has non-uniform binning


  o LinkDef3

    - Add dictionary for RooCacheManager<vector<double> >
