//! flat_set is a Sorted Associative Container that stores objects of type Key.
//! flat_set is a Simple Associative Container, meaning that its value type,
//! as well as its key type, is Key. It is also a Unique Associative Container,
//! meaning that no two elements are the same.
//!
//! flat_set is similar to std::set but it's implemented like an ordered vector.
//! This means that inserting a new element into a flat_set invalidates
//! previous iterators and references
//!
//! Erasing an element of a flat_set invalidates iterators and references
//! pointing to elements that come after (their keys are bigger) the erased element.

//! flat_multiset is a Sorted Associative Container that stores objects of type Key.
//! flat_multiset is a Simple Associative Container, meaning that its value type,
//! as well as its key type, is Key.
//! flat_Multiset can store multiple copies of the same key value.
//!
//! flat_multiset is similar to std::multiset but it's implemented like an ordered vector.
//! This means that inserting a new element into a flat_multiset invalidates
//! previous iterators and references
//!
//! Erasing an element of a flat_multiset invalidates iterators and references
//! pointing to elements that come after (their keys are equal or bigger) the erased element.
