Sometimes in single hist fits with maximum-likelihood musrfit prints

PRunSingleHisto::CalcMaxLikelihood: WARNING NEGATIVE theory!! ...
and never reaches convergence, so fits appear to hang on repeated messages.

Maybe consider giving up at some point and report no convergence. Typically switching to chi2 and then back to maximum-likelihood works.
