Example
-------

Example how to use the minimizers in an IceTray script::

    # Add the standard gulliver service factories.
    tray.AddService("I3SimpleParametrizationFactory", "param", ...)
    tray.AddService("I3RecoLLHFactory", "pandel", ...)
    tray.AddService("I3BasicSeedServiceFactory", "seed", ...)

    # Add the python class directly into the tray's context
    # (no need for a service factory).
    tray.context["iminuit"] = lilliput.IMinuitMinimizer(tolerance=0.001)

    # Now call the gulliver module in the normal way.
    tray.AddModule("I3SimpleFitter", "singlefit",
                   SeedService="seed",
                   Parametrization="param",
                   LogLikelihood="pandel",
                   Minimizer="iminuit")
