17// -- CLASS DESCRIPTION [AUX] --
18// RooMapCatEntry is an auxilary class for RooMappedCategory and defines a
19// a mapping. A mapping consists of a wildcard regular expression, that
20// can be matched against the input category state label and an output
21// category state (RooCatType), which should be assign if the match is successfull.
