class ROOT::Minuit2::MinuitParameter


    class for the individual Minuit Parameter with Name and number;
    contains the input numbers for the minimization or the output result
    from minimization;
    possible interactions: Fix/release, set/remove limits, set Value/error;

    From version 5.20: use string to store the name to avoid limitation of
    name length of 20 characters

This class is also known as (typedefs to this class)
