/**
 * This is the base class inherited by all (JS) views. Odoo JS views are the
 * widgets used to display information in the main area of the web client
 * (note: the search view is not a "JS view" in that sense).
 *
 * The abstract view role is to take a set of fields, an arch (the xml
 * describing the view in db), and some params, and then, to create a
 * controller, a renderer and a model.  This is the classical MVC pattern, but
 * the word 'view' has historical significance in Odoo code, so we replaced the
 * V in MVC by the 'renderer' word.
 *
 * JS views are supposed to be used like this:
 * 1. instantiate a view with some arch, fields and params
 * 2. call the getController method on the view instance. This returns a
 *    controller (with a model and a renderer as sub widgets)
 * 3. append the controller somewhere
 *
 * Note that once a controller has been instantiated, the view class is no
 * longer useful (unless you want to create another controller), and will be
 * in most case discarded.
