Description of calc_hyperparameter

DESCRIPTION

 CALC_HYPERPARAMETER: calculate hyperparameter value
   The hyperparameter is can be either provided directly,
     or can be based an automatic selection approach
 
 calc_hyperparameter can be called as
    hyperparameter= calc_hyperparameter( inv_model )
 where inv_model    is an inv_model structure

 if inv_model.hyperparameter.func exists, it will be
   called, otherwise inv_model.hyperparameter.value will
   be returned

 TODO: does hyperparameter depend on inv_model, or does
       it also depend on the data?
