Corrects turbulence viscosity field (e.g. nut) within a specified
region by applying a maximum limit, set according to a coefficient
multiplied by the laminar viscosity:

    \nu_{t,max} = c \nu

Corrections applied to:

  nut  | Turbulence vicosity                   [m2/s2]

Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    limitTurbulenceViscosity1
    {
        // Mandatory entries (unmodifiable)
        type            limitTurbulenceViscosity;

        // Optional entries (runtime modifiable)
        nut             nut;
        c               1e5;

        // Mandatory/Optional (inherited) entries
        ...
    }
