A nonlinear mixed-effects structure is a list of model components
representing different sets of parameters in the nonlinear mixed-effects
model. An nlmeStruct list must contain at least a
reStruct object, but may also contain corStruct and
varFunc objects. NULL arguments are not included in the
nlmeStruct list.
