//! \file
//! This header file forward declares most Intrusive classes.
//!
//! It forward declares the following containers and hooks:
//!   - boost::intrusive::slist / boost::intrusive::slist_base_hook / boost::intrusive::slist_member_hook
//!   - boost::intrusive::list / boost::intrusive::list_base_hook / boost::intrusive::list_member_hook
//!   - boost::intrusive::bstree / boost::intrusive::bs_set / boost::intrusive::bs_multiset /
//!      boost::intrusive::bs_set_base_hook / boost::intrusive::bs_set_member_hook

//!      boost::intrusive::unordered_set_base_hook / boost::intrusive::unordered_set_member_hook / 
//!   - boost::intrusive::any_base_hook / boost::intrusive::any_member_hook
//!
//! It forward declares the following container or hook options:
//!   - boost::intrusive::constant_time_size / boost::intrusive::size_type / boost::intrusive::compare / boost::intrusive::equal
//!   - boost::intrusive::floating_point / boost::intrusive::priority / boost::intrusive::hash
//!   - boost::intrusive::value_traits / boost::intrusive::member_hook / boost::intrusive::function_hook / boost::intrusive::base_hook
//!   - boost::intrusive::void_pointer / boost::intrusive::tag / boost::intrusive::link_mode
//!   - boost::intrusive::optimize_size / boost::intrusive::linear / boost::intrusive::cache_last

//!   - boost::intrusive::power_2_buckets / boost::intrusive::cache_begin / boost::intrusive::compare_hash / boost::intrusive::incremental
//!
//! It forward declares the following value traits utilities:
//!   - boost::intrusive::value_traits / boost::intrusive::derivation_value_traits /
//!      boost::intrusive::trivial_value_traits
//!
//! Finally it forward declares the following general purpose utilities:
//!   - boost::intrusive::pointer_plus_bits / boost::intrusive::priority_compare.
