// Module: EvtBody3.cc  //Modified Body3 model
//
// usage:
// Users need to provide the MC and data file in NTuple style. The decays are described as
//                        A->  x1    +   x2     +  x3
//angular distribution:    costheta1, costheta2 ,costheta3
// mass distribution:          m12, m13, and m23, here, m12 ==> mass of x1 and x2, etc.
// these variables are defined as double type, the tree name is mc and data, repectively
