Extract gnls Coefficients

Description:

     The estimated coefficients for the nonlinear model represented by
     'object' are extracted.

Usage:

     ## S3 method for class 'gnls':
     coef(object, ...)

Arguments:

  object: an object inheriting from class 'gnls', representing a
          generalized nonlinear least squares fitted model.

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

Value:

     a vector with the estimated coefficients for the nonlinear model
     represented by 'object'.
