//********************************************************************************
//
// Description:
//   A collection cut minimal selection cuts.
//   These selection cuts are intended to be simple selections on kinematic variables.
//   The cuts are ANDed together
//   intended use case cuts on et and eta
//   However individual cuts can be skipped, so you can disable say only the Et cut
//   when  you're doing a turn on
//
// Implimentation:
//   Basically a vector of VarRangeCuts which a nice operator() function to make it
//   easy to use
//
