23 RooCmdArg is a named container for two doubles, two integers
24 two object points and three string pointers that can be passed
25 as generic named arguments to a variety of RooFit end user
26 methods. To achieved the named syntax, RooCmdArg objects are
27 created using global helper functions defined in RooGlobalFunc.h
28 that create and fill these generic containers
