[GrzLinModel] Modifying default optimization algorithm

Description

Package GrzLinModel can use all ​NLopt algorithms by means of NonLinGloOpt but, sometimes user cannot specify what algorithm wants to use or doesn't know how to do it.

A simple solution is to create an static member with the default method before to call estimation methods.

Problem has been solved in GrzLinModel.4.1 that requires tol v3.1 b002

For example if you want to use ​Preconditioned truncated Newton, you can write this line before to call the estimation method:

Real GrzLinModel::@WgtReg::default.NonLinGloOpt.Algorithm := 
  NonLinGloOpt::Algorithm::LD_TNEWTON_PRECOND_RESTART;
