The cross sections for pion nucleon -> pion kaon lambda and pion nucleon -> pion kaon sigma

The cross sections

• pion nucleon -> pion kaon lambda

and

• pion nucleon -> pion kaon sigma

have been implemented in revision r2636 according to K. Gallmeister's fits to pi⁺p and pi^-p data. You find those fits in the module parametrizationBarMes.f90.
