 - Add a Scalar typedef definition in the TVectors  in order to use the ROOT::Math::VectorUtil functions
 - Fix a bug introduced in the Choleski decomposition for making it compiling with Vc. This fixes the testInversion test

  using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.

Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.

Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

Introduce alternative cmake based build system. Cmake is especially convenient
for building on Windows, as it can produce VC projects or nmake files and 
does not require cygwin to be installed. In addition on OSX Xcode projects
can be generated.

To make an out of source build do, assuming the source is in ~/root:
   mkdir ~/root-x8664
   cd ~/root-x8664
   ~/root/configure
   make
This is convenient to build e.g. 32 and 64-bit version from one source, but
also needed for cross-compilation, where it is now possible to build in
a special directory only the compile time tools, like rootcint for the
host architecture while the binary is build for the remote architecture
(like iOS).

I'd like to suggest to improve the TLorentzVector outputmessage printed calling the ::Print() method. In all the current versions the TLorentzVector print just a static message with the class description. 
I'm proposing a very simple change, similar to what TVector3 does, that for each vector prints the content in (x,y,z,t) form and (P,eta,phi,E) form.

This patch fixes the spelling of "function" in the root source code
and documentation, which is misspelled (sometimes as part of larger
"function"-based words) at least 152 times:

* "funciton" 48 times
* "funcion" 36 times
* "funtion" 23 times
* "fucntion" 17 times
* "functionn" 6 times
* "fuction" 6 times
* "fuunction" 4 times
* "functioin" 3 times
* "fonction" 3 times
* "funstion" twice
* "fnuction" once
* "functiom" once
* "functio" once
* "funcition" once

* New user interface:

The old user interface was very hard to use, and the documentation in the source was also not on par with the correct usage. The old interface was a single get-function with 12 arguments, and the user was supposed to figure out which ~ 5 arguments were relevant for a specific model (1 out of 7 models).
The new user interface is is easy to use correctly and hard to use incorrectly (TM). It's a single set-method for each method:

SetPoissonBkgBinomialEff(Int_t x,Int_t y,Int_t z,Double_t tau,Int_t m);
SetPoissonBkgGaussianEff(Int_t x,Int_t y,Double_t em, Double_t tau,Double_t sde);
SetGaussianBkgGaussianEff(Int_t x,Double_t bm,Double_t em, Double_t sde,Double_t sdb);
SetPoissondBkgknownEff(Int_t x,Int_t y,Double_t tau,Double_t e);
SetGaussianBkgknownEff(Int_t x,Double_t bm,Double_t sdb,Double_t e);
SetKnownBkgBinomialEff(Int_t x, Int_t z,Int_t m,Double_t b);
SetknownBkgGaussianEff(Int_t x,Double_t em,Double_t sde,Double_t b);


* New methods for getting:

- 'sensitivity' (average limits) and related quantities
- 'critical number' related to rejection of the null-hypothesis
 (no signal).

* Bug fixes. There was a few bugs in that some variables was used
 uninitialized. (Eg, input arguments which were not supposed to be
 used were used anyway.)
