TH1::Fit(const Text_t *fname .. ) is an extremely useful and simple tool
to access Minuit. It has an implementation for setting ParLimits.
I think fixing parameters (gMinuit->mnfixp) would also be useful and
quite simple to implement (just along the lines SetParLimits works).
mnfree is probably not needed at this level since a new invocation of
TH1::Fit without fixing does the required job.
Cheers,
Otto
