Description
GModels is actually derived from GOptimizerPars, yet both are container classes for different things. GModels contains models while GOptimizerPars contains parameters.
The relation between GModels and GOptimizerPars should be rethought to see if a more logical and clearer relationship can be defined. This will not change the actual workings, but should make the code more clear.
Recurrence
No recurrence.

GModelPar method are actually used by GOptimizerLM:
isfree()fix()name()factor_gradient()factor_value()factor_min()factor_max()hasmin()hasmax()factor_error()
Hence only a small subset of the GModelPar methods are not used.
So I suggest to introduce a GOptimizerPar method from which GModelPar will derive (eventually, GModelPar may disappear later).
GOptimizerPars should then became a real container class of GOptimizerPar objects (the container will hold pointers to these objects).
GModels will not derive from GOptimizerPars but will have a method that returns a GOptimizerPars object containing pointers to the model parameters in GModels. This needs some logic that GOptimizerPars can handle internally allocated parameters, but also externally managed parameters.

GModels no longer derives from GOptimizerPars. The implementation of GOptimizerPars as standalone container has started. The GModels::pars() method now extract the model parameters as a flat array into a GOptimizerPars instance.
GOptimizerPars is a container of GOptimizerPar objects. GModelPar now derives from GOptimizerPar.

The GOptimizerPars class is not fully complete. Also NEWS / ChangeLog need to be updated.
