+ //! and false. If there is not equivalent key can be inserted returns true
+ //! in the returned pair's boolean and fills "commit_data" that is meant to
+ //! be used with the "insert_commit" function to achieve a constant-time
+ //! insertion function.
+ //!
+ //! <b>Complexity</b>: Average complexity is at most logarithmic.
+ //!
+ //! <b>Throws</b>: If "comp" throws.
+ //!
+ //! <b>Notes</b>: This function is used to improve performance when constructing
+ //! a node is expensive and the user does not want to have two equivalent nodes
+ //! in the tree: if there is an equivalent value
+ //! the constructed object must be discarded. Many times, the part of the
+ //! node that is used to impose the order is much cheaper to construct
+ //! than the node and this function offers the possibility to use that part
+ //! to check if the insertion will be successful.
+ //!
+ //! If the check is successful, the user can construct the node and use
+ //! "insert_commit" to insert the node in constant-time. This gives a total
+ //! logarithmic complexity to the insertion: check(O(log(N)) + commit(O(1)).
+ //!
+ //! "commit_data" remains valid for a subsequent "insert_unique_commit" only
+ //! if no more objects are inserted or erased from the set.

+//! The class template hashtable is an intrusive hash table container, that
+//! is used to construct intrusive unordered_set and unordered_multiset containers. The
+//! no-throw guarantee holds only, if the Equal object and Hasher don't throw.
+//!
+//! hashtable 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: hashtable 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
+//! hashtable 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<>, power_2_buckets<>, cache_begin<> and incremental<>.
+//!
+//! hashtable 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 hashtables because several
+//! key functions, like "empty()", become non-constant time functions. Non
+//! constant_time size hashtables are mainly provided to support auto-unlink hooks.
+//!
+//! hashtables, 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 rehashing.
