Generalized Nonlinear Least Squares Structure
.DN
A generalized nonlinear least squares structure is a list of model
components representing different sets of parameters in the nonlinear 
model. A `gnlsStruct'  may contain `corStruct' and
`varFunc' objects. `NULL' arguments are not included in the
`gnlsStruct' list.

gnlsStruct(corStruct, varStruct)
.OA
.AG corStruct
an optional `corStruct' object, representing a
correlation structure. Default is `NULL'.
.AG varStruct
an optional `varFunc' object, representing a
variance function structure. Default is `NULL'.
.RT
a list of model variance-covariance components determining the
parameters to be estimated for the associated nonlinear model.
