0009    \brief   Class derived from the TopGenEvent for single-top events
0010
0011    The structure holds reference information to the generator particles
0012    of the decay chains for each top quark and of the initial partons
0013    and provides access and administration. The derived class contains
0014    a few additional getters with respect to its base class.
