// Class AliRsnHistoDef
//
// Definition for a histogram type.
// Since one could do an analysis which is not an invariant mass
// the histogram definition should be more flexible, and it is stored
// separately in a new class.
// This class considers the possibility of a 1D or 2D histograms
// with its related binning, and can create a new histo from his definitions
//
