Simplify access to Normalized name

now it's only necessary to have the decl and the interpreter.
Use simplified GetNormalizedName interface
Correct name of warning emitter
Adjust routines following ROOT-5906

now the template parameters are not reconstructed using the source
manager (and therefore vulnerable to, for example, preprocessor
statements) but the template parameters accessed through the clang
API.
In presence of a non strongly typed enum as template parameter
the forward declaration is bailed out since it is not possible
to have one. The transition to c++11 and strongly typed enums
will allow the forward declaration of those.

Protect in case of only 1 point. Fix ROOT-5397
Fix a bug (ROOT-5200) in computing the bin errors in TH2::Smooth
Apply fixes for ROOT-5058

Add SetBins method in TEfficiency
Add new methods CreateGraph and CreateHistogram which create the histograms used to paint the class. They can now be called without drawing it.
Fix a couple of tutorials.
Merge branch 'master' of https://root.cern.ch/git/root
Update cocoa tutorials to make it possible run them all in one session (before

they were using the same color indices for custom colors and this was not good at all).
Also, make these tutorials look more ... modern (?) and reasonable, add some primitive error handling at least.
FindFreeCustomColorIndex - scan gROOT's color indices and search the first free (in some hardcoded range).
Remove forgotten printout
Adding copy constructors to build models using python more robustly.
bugfixes. Fix HF for models without any nuisance parameters.
Bugfix copy constructor for non-counting models.
Recognise and don't fwd declare variadic templates
When checking consistency of histogram (e.g. in TH1::Add)  check only the relevant axis (e.g ignore y and z axis for 1D histos)/
this fix ROOT-5249
Add an error messages in the TH1 methods which makes sense only for 1D histogram, like TH1::GetBinCenter.
This fixes ROOT-5049
Update documentation of TH1::KolmogorovTest as suggested in ROOT-4888
