RooDataHist::printDataHistogram was recently added to print the bin contents of a RooDataHist. While very useful, this function needs several changes:

• The observable should not be passed as an argument. Rather, the histogram already knows its observables and could behave accordingly.
• The current implementation does not work for histograms with more than 1 observable
• The function should be renamed to printContents and moved upwards the inheritance hierarchy to instead be declared in RooAbsData. A version for RooDataSet should be implemented as well.
