This is the base class for the three meson decays of the weak current.
It is designed so that the currents for the following modes can be implemented in classes inheriting from this
obviously there are other modes with three pseudoscalar mesons for the decay of the weak current but this model original came from decay where these are the only modes. However one case which is important is the inclusion of the mixing in the neutral kaon sector for which we include the additional currents
, (imode=11)
In this case the current is given by
