Test point generation for processes with decays

[Stefan Hoeche]

At the moment the TestPoint routine of the phase space handler does not respect on-shell constraints for intermediate resonances when generating processes with decay chains in Amegic or Comix. Thus the gauge test is meaningless, because the intermediate particle will in general be far off-shell. To avoid irritating error messages (actually not indicating an error at all) and to introduce a meaningful gauge test for processes including decays, we should construct the test point successively, following the decay tree of the process. This can be done using the Process_Info, i.e. no additional information from the matrix element generator is required.
