_D_e_s_c_r_i_p_t_i_o_n:

     'Pars' is used to update the coefficients of the model components
     of 'object' and the individual log-likelihood contributions of
     each component are added together.

_U_s_a_g_e:

     ## S3 method for class 'gnlsStruct':
     logLik(object, Pars, conLin, ...)

_A_r_g_u_m_e_n_t_s:

  object: an object inheriting from class 'gnlsStruct', representing a
          list of model components, such as 'corStruct' and 'varFunc'
          objects, and attributes specifying the underlying nonlinear
          model and the response variable.

    Pars: the parameter values at which the log-likelihood is to be
          evaluated.

  conLin: an optional condensed linear model object, consisting of a
          list with components '"Xy"', corresponding to a regression
          matrix ('X') combined with a response vector ('y'), and 
          '"logLik"', corresponding to the log-likelihood of the
          underlying nonlinear model. Defaults to 'attr(object,
          "conLin")'.

     ...: some methods for this generic require additional arguments. 
          None are used in this method.

_V_a_l_u_e:

     the log-likelihood for the linear model described by 'object',
     evaluated at 'Pars'.
