Iterface to NewMinuit

[eacharles]

As per Jean

Among the three suggestions in my C&A presentation (in bold at https://confluence.slac.stanford.edu/display/SCIGRPS/Convergence+issues+for+4FGL), only one remains standing.
It would be very convenient if there existed an interface allowing to retrieve the convergence status of NewMinuit, similar to that for Minuit (below), because NewMinuit is about twice faster than Minuit.
Is that something doable?
Happy 2020,

import pyLikelihood as pyLike
like = BinnedAnalysis(..., optimizer="Minuit")

myqual=pyLike.Minuit(like.logLike)
like.fit(covar=True, optObject=myqual)
qual=myqual.getQuality()

or if optObject was not set in the like.fit call

like.fit(covar=True)
quality = pyLike.Minuit.cast(like.optObject).getQuality()
