\title{R6 class representing a (generic) model.}
\description{
"Model" class, containing a (generic) learning function, which from
data + target [+ params] returns a prediction function X --> y.
Parameters for cross-validation are either provided or estimated.
Model family can be chosen among "rf", "tree", "ppr" and "knn" for now.
