implemented needed function in SimplCacheSentry
PDFs for reading Atlas workspaces
Merge branch 'Combine620SimpleCacheSentryFix' of https://github.com/andersonjacob/HiggsAnalysis-CombinedLimit
Merge branch 'AtlasPdfs-development61X' of https://github.com/gpetruc/HiggsAnalysis-CombinedLimit
remove stray comma, spotted by gcc48
move AtlasPdfs into interface, to make the MakeFile easier
FastComplexErrFunc -> ComplexErrFuncFast in new RooFit
Makefile updated and working (slc6, gcc481, root 5.34.17)
fix python path
Link also against libHistFactory to get dictionaries for those classes as well (needed by Atlas)
Allow loading the dataset from a different file by using -D file:dataset or -D file:workspace:dataset; also fix Makefile for recompiling
fix clone constructors, needed for text2workspace in 5.34.17 (but should be backwards compatible)
Add a static method to convert a Gaussian into a SimpleGaussianConstraint when possible, used to optimize ATLAS+CMS workspaces at combination time. Implementation could be improved avoiding the need to throw an exception.
Update with anything new in development branch
Merge pull request #125 from gpetruc/standalone-slc6-gcc48-root5.34.17

slc6  fixes, makefile that works for standalone compilation, pdfs needed for atlas workspaces
