Hi,

I just browsed the new interface classes TVirtualFitter and TFitter.
I think there should be a method like Fit() in it. If I e.g. set want
a log likelihood fit to event data not to an histogram, it seems to be
possible with that interface to setup my own log likelihood function.
I can specify my initial parameters and so on. 
But for the last step, the actual fitting there is no interface
function and I have to call the actual fitter via the Fortran-like
ExecuteCommand() method.

Why not include a Fit() methods which hides the concrete command (Migrad
in the
case of Minuit) too.

Peter
