0006 // Description:
0007 //   A collection cut minimal selection cuts.
0008 //   These selection cuts are intended to be simple selections on kinematic variables.
0009 //   The cuts are ANDed together
0010 //   intended use case cuts on et and eta
0011 //   However individual cuts can be skipped, so you can disable say only the Et cut
0012 //   when  you're doing a turn on
0013 //
0014 // Implimentation:
0015 //   Basically a vector of VarRangeCuts which a nice operator() function to make it
0016 //   easy to use
