// This cut definition works on mini-pairs for the 'mini' subpackage.
// Since cuts on mini-pairs can usually be just kinematic selections
// or kinematic comparisons between 4-momenta of daughters, they are all
// implemented in this class, by the use of an enumeration which allows
// the user to choose between all possibilities.
