Add this as well, and you should be able to use a scalar Constant as
if it was a double:

    /// Scalar conversion operator
    operator double() const
    {
        if(_size > 1)
            error("Cannot convert non-scalar Constant to a double.");
        return _values[0];
    }

I won't commit this myself since I currently can't compile dolfin,
it complains about program_options although I have it and use
it in some syfi demos. Probably the same as someone else
experienced, but I don't have time to figure it out now.
