//! rbtree_algorithms provides basic algorithms to manipulate
//! nodes forming a red-black tree. The insertion and deletion algorithms are
//! based on those in Cormen, Leiserson, and Rivest, Introduction to Algorithms
//! (MIT Press, 1990), except that
//!
//! (1) the header node is maintained with links not only to the root
//! but also to the leftmost node of the tree, to enable constant time
//! begin(), and to the rightmost node of the tree, to enable linear time
//! performance when used with the generic set algorithms (set_union,
//! etc.);
//!
//! (2) when a node being deleted has two children its successor node is
//! relinked into its place, rather than copied, so that the only
//! pointers invalidated are those referring to the deleted node.
//!
//! rbtree_algorithms is configured with a NodeTraits class, which encapsulates the
//! information about the node to be manipulated. NodeTraits must support the
//! following interface:
//!
//! <b>Typedefs</b>:
//!
//! <tt>node</tt>: The type of the node that forms the binary search tree
//!
//! <tt>node_ptr</tt>: A pointer to a node
//!
//! <tt>const_node_ptr</tt>: A pointer to a const node
//!
//! <tt>color</tt>: The type that can store the color of a node
//!
//! <b>Static functions</b>:
//!
//! <tt>static node_ptr get_parent(const_node_ptr n);</tt>
//!
//! <tt>static void set_parent(node_ptr n, node_ptr parent);</tt>
//!
//! <tt>static node_ptr get_left(const_node_ptr n);</tt>
//!
//! <tt>static void set_left(node_ptr n, node_ptr left);</tt>

//! treap_algorithms provides basic algorithms to manipulate
//! nodes forming a treap.
//!
//! (1) the header node is maintained with links not only to the root
//! but also to the leftmost node of the tree, to enable constant time
//! begin(), and to the rightmost node of the tree, to enable linear time
//! performance when used with the generic set algorithms (set_union,
//! etc.);
//!
//! (2) when a node being deleted has two children its successor node is
//! relinked into its place, rather than copied, so that the only
//! pointers invalidated are those referring to the deleted node.
//!
//! treap_algorithms is configured with a NodeTraits class, which encapsulates the
//! information about the node to be manipulated. NodeTraits must support the
//! following interface:
//!
//! <b>Typedefs</b>:
//!
//! <tt>node</tt>: The type of the node that forms the treap
//!
//! <tt>node_ptr</tt>: A pointer to a node
//!
//! <tt>const_node_ptr</tt>: A pointer to a const node
//!
//! <b>Static functions</b>:
//!
//! <tt>static node_ptr get_parent(const_node_ptr n);</tt>
//!
//! <tt>static void set_parent(node_ptr n, node_ptr parent);</tt>

//! The class template unordered_set is an intrusive container, that mimics most of
//! the interface of std::tr1::unordered_set as described in the C++ TR1.
//!
//! unordered_set is a semi-intrusive container: each object to be stored in the
//! container must contain a proper hook, but the container also needs
//! additional auxiliary memory to work: unordered_set needs a pointer to an array
//! of type `bucket_type` to be passed in the constructor. This bucket array must
//! have at least the same lifetime as the container. This makes the use of
//! unordered_set more complicated than purely intrusive containers.
//! `bucket_type` is default-constructible, copyable and assignable
//!
//! The template parameter \c T is the type to be managed by the container.
//! The user can specify additional options and if no options are provided
//! default options are used.
//!
//! The container supports the following options:
//! \c base_hook<>/member_hook<>/value_traits<>,
//! \c constant_time_size<>, \c size_type<>, \c hash<> and \c equal<>
//! \c bucket_traits<>, \c power_2_buckets<> and \c cache_begin<>.
//!
//! unordered_set only provides forward iterators but it provides 4 iterator types:
//! iterator and const_iterator to navigate through the whole container and
//! local_iterator and const_local_iterator to navigate through the values
//! stored in a single bucket. Local iterators are faster and smaller.
//!
//! It's not recommended to use non constant-time size unordered_sets because several
//! key functions, like "empty()", become non-constant time functions. Non
//! constant-time size unordered_sets are mainly provided to support auto-unlink hooks.
//!
//! unordered_set, unlike std::unordered_set, does not make automatic rehashings nor
//! offers functions related to a load factor. Rehashing can be explicitly requested
//! and the user must provide a new bucket array that will be used from that moment.
//!
//! Since no automatic rehashing is done, iterators are never invalidated when
//! inserting or erasing elements. Iterators are only invalidated when rehasing.

//! The class template unordered_multiset is an intrusive container, that mimics most of
//! the interface of std::tr1::unordered_multiset as described in the C++ TR1.
//!
//! unordered_multiset is a semi-intrusive container: each object to be stored in the
//! container must contain a proper hook, but the container also needs
//! additional auxiliary memory to work: unordered_multiset needs a pointer to an array
//! of type `bucket_type` to be passed in the constructor. This bucket array must
//! have at least the same lifetime as the container. This makes the use of
//! unordered_multiset more complicated than purely intrusive containers.
//! `bucket_type` is default-constructible, copyable and assignable
//!
//! The template parameter \c T is the type to be managed by the container.
//! The user can specify additional options and if no options are provided
//! default options are used.
//!
//! The container supports the following options:
//! \c base_hook<>/member_hook<>/value_traits<>,
//! \c constant_time_size<>, \c size_type<>, \c hash<> and \c equal<>
//! \c bucket_traits<>, \c power_2_buckets<> and \c cache_begin<>.
//!
//! unordered_multiset only provides forward iterators but it provides 4 iterator types:
//! iterator and const_iterator to navigate through the whole container and
//! local_iterator and const_local_iterator to navigate through the values
//! stored in a single bucket. Local iterators are faster and smaller.
//!
//! It's not recommended to use non constant-time size unordered_multisets because several
//! key functions, like "empty()", become non-constant time functions. Non
//! constant-time size unordered_multisets are mainly provided to support auto-unlink hooks.
//!
//! unordered_multiset, unlike std::unordered_set, does not make automatic rehashings nor
//! offers functions related to a load factor. Rehashing can be explicitly requested
//! and the user must provide a new bucket array that will be used from that moment.
//!
//! Since no automatic rehashing is done, iterators are never invalidated when
//! inserting or erasing elements. Iterators are only invalidated when rehasing.
