//! A flat_map is a kind of associative container that supports unique keys (contains at
//! most one of each key value) and provides for fast retrieval of values of another
//! type T based on the keys.
//!
//! A flat_map satisfies all of the requirements of a container, a reversible
//! container and an associative container. A flat_map also provides
//! most operations described for unique keys. For a
//! flat_map<Key,T> the key_type is Key and the value_type is std::pair<Key,T>
//! (unlike std::map<Key, T> which value_type is std::pair<<b>const</b> Key, T>).
//!
//! flat_map is similar to std::map but it's implemented by as an ordered sequence container.
//! The underlying sequence container is by default <i>vector</i> but it can also work
//! user-provided vector-like SequenceContainers (like <i>static_vector</i> or <i>small_vector</i>).
//!
//! Using vector-like sequence containers means that inserting a new element into a flat_map might invalidate
//! previous iterators and references (unless that sequence container is <i>stable_vector</i> or a similar
//! container that offers stable pointers and references). Similarly, erasing an element might invalidate
//! iterators and references pointing to elements that come after (their keys are bigger) the erased element.
//!
//! This container provides random-access iterators.
//!
//! \tparam Key is the key_type of the map
//! \tparam Value is the <code>mapped_type</code>
//! \tparam Compare is the ordering function for Keys (e.g. <i>std::less<Key></i>).
//! \tparam AllocatorOrContainer is either:
//! - The allocator to allocate <code>value_type</code>s (e.g. <i>allocator< std::pair<Key, T> > </i>).
//! (in this case <i>sequence_type</i> will be vector<value_type, AllocatorOrContainer>)
//! - The SequenceContainer to be used as the underlying <i>sequence_type</i>. It must be a vector-like
//! sequence container with random-access iterators..

//! A flat_multimap is a kind of associative container that supports equivalent keys
//! (possibly containing multiple copies of the same key value) and provides for
//! fast retrieval of values of another type T based on the keys.
//!
//! A flat_multimap satisfies all of the requirements of a container and of a reversible
//! container and of an associative container. For a
//! flat_multimap<Key,T> the key_type is Key and the value_type is std::pair<Key,T>
//! (unlike std::multimap<Key, T> which value_type is std::pair<<b>const</b> Key, T>).
//!
//! flat_multimap is similar to std::multimap but it's implemented by as an ordered sequence container.
//! The underlying sequence container is by default <i>vector</i> but it can also work
//! user-provided vector-like SequenceContainers (like <i>static_vector</i> or <i>small_vector</i>).
//!
//! Using vector-like sequence containers means that inserting a new element into a flat_multimap might invalidate
//! previous iterators and references (unless that sequence container is <i>stable_vector</i> or a similar
//! container that offers stable pointers and references). Similarly, erasing an element might invalidate
//! iterators and references pointing to elements that come after (their keys are bigger) the erased element.
//!
//! This container provides random-access iterators.
//!
//! \tparam Key is the key_type of the map
//! \tparam Value is the <code>mapped_type</code>
//! \tparam Compare is the ordering function for Keys (e.g. <i>std::less<Key></i>).
//! \tparam AllocatorOrContainer is either:
//! - The allocator to allocate <code>value_type</code>s (e.g. <i>allocator< std::pair<Key, T> > </i>).
//! (in this case <i>sequence_type</i> will be vector<value_type, AllocatorOrContainer>)
//! - The SequenceContainer to be used as the underlying <i>sequence_type</i>. It must be a vector-like
//! sequence container with random-access iterators.
