Recalculate for a modelStruct Object

Description:

     This method function recalculates the condensed linear model
     object using each element of 'object' sequentially from last to
     first.

Usage:

     ## S3 method for class 'modelStruct':
     recalc(object, conLin, ...)

Arguments:

  object: an object inheriting from class 'modelStruct', representing a
          list of model components, such as 'corStruct' and 'varFunc'
          objects.

  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 model. Defaults to 'attr(object, "conLin")'.

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

Value:

     the recalculated condensed linear model object.

Note:

     This method function is generally only used inside model fitting
     functions, such as 'lme' and 'gls', that allow model components,
     such as correlated error terms and variance functions.
