New JpsiKst[KPi0] with generator-level cuts

Maximilien Chefdeville requested to merge chefdevi/my-jpsikst2kpi0 into master

This is a modification of 12143401 (Bu_JpsiKst,mm,Kpi0=DecProdCut) with generator-level LoKi cuts added, resulting in 3 times higher statistics.

Running Gauss with 50 events, we find the following generator efficency: eff = 24/419 = 5.7 +/- 1.2 % and 22 s/evt.

To be compared with the original decfile without cuts: eff = 26/148 = 16.4 +/- 3.0 % and 9 s/evt.

Attached are the Gauss test and generator logs.

Subsequent MC tupling showed that the photon PT cuts are well applied.
