//! defines an abstract owner of sensitive primitives.
//! Owners are typically used to establish a connection
//! between sensitive entities and high-level objects (e.g. presentations).
//!
//! Priority : It's possible to give a priority:
//! the scale : [0-9] ; the default priority is 0
//! it allows the predominance of one selected object upon
//! another one if many objects are selected at the same time
//!
//! example : Selection of shapes : the owners are
//! selectable objects (presentations)
//!
//! a user can give vertex priority [3], edges [2] faces [1] shape [0],
//! so that if during selection one vertex one edge and one face are
//! simultaneously detected, the vertex will only be hilighted.
