Multidimensional models: multi-dimensional pdfs through composition e.g.
substituting a pdf parameter with a function that depends on other observables
pdf = gauss(x,f(y),s)
with f(y) = a0 + a1*y

RooArgSet is a container object that can hold multiple RooAbsArg objects.
Plot frame and a container for graphics objects within that frame.
A RooAbsReal implementing a polynomial in terms of a list of RooAbsReal coefficients.
Variable that can be changed from the outside.
TH1 is the base class of all histogram classes in ROOT.
