Generator iterating eternally

Description

Dear developpers,

I got a problem when choosing a parameter (alpha) for BelleNR amplitude. When this parameter is too big, and thus events at high mass become too rare, the generator starts iterating ad vitam eternam without stopping...:

ERROR in LauAbsFitModel::generate : Problem in toy MC generation. Starting again with updated parameters... INFO in LauAbsFitModel::generate : Generating experiment number 0

In this case, the generation problem is due to the aSqMax limit.

Cheers A.Hicheur

Resetting the max number of iterations in LauIsobarDynamics::checkToyMC does improve things but then the generation is done after quiet a long time.

The suggestion would be to trigger a warning message about e.g., a too diverging amplitude, possibly with the position in DP, so that the user knows more precisely what is happening.
