//! A SelectSuite can describe a suite of SelectDeduct as a unique
//! one : in other words, it can be seen as a "macro selection"
//!
//! It works by applying each of its items (which is a
//! SelectDeduct) on the result computed by the previous one
//! (by using Alternate Input)
//!
//! But each of these Selections used as items may be used
//! independently, it will then give its own result
//!
//! Hence, SelectSuite gives a way of defining a new Selection
//! from existing ones, without having to do copies or saves
