  object: an object.

_D_e_t_a_i_l_s:

     'refit' is a new generic function for refitting a certain model
     object on multiple versions of a data set (and is hence different
     from 'update'). Applications are partitioned/segmented models
     where the same type of model should be refitted on each sub-sample
     or partition. See 'fxregimes' for such an example. Another
     application would be reweighted models such as in mixture models.

     The generic is similar to the one provided in 'modeltools' (and
     should fulfill the same purpose). To avoid dependence on this
     package, it is also provided here.
