-- - opt::compare - key comparison functor. No default functor is provided.
-- If the option is not specified, the opt::less is used.
-- - opt::less - specifies binary predicate used for key comparison. Default is \p std::less<T>.
-- - opt::back_off - back-off strategy used. If the option is not specified, the cds::backoff::Default is used.
-- - opt::disposer - the functor used for dispose removed items. Default is opt::v::empty_disposer. Due the nature
-- of GC schema the disposer may be called asynchronously.
-- - opt::link_checker - the type of node's link fields checking. Default is \ref opt::debug_check_link
-- - opt::item_counter - the type of item counting feature. Default is \ref atomicity::empty_item_counter that is no item counting.
-- - opt::memory_model - C++ memory ordering model. Can be opt::v::relaxed_ordering (relaxed memory model, the default)
-- or opt::v::sequential_consistent (sequentially consisnent memory model).

\par Usage
There are different specializations of this template for each garbage collecting schema used.
See \ref cds_intrusive_MichaelList_nogc "non-GC MichaelList"
Then, you should incorporate michael_list::node into your struct \p T and provide
-- appropriate michael_list::type_traits::hook in your \p Traits template parameters. Usually, for \p Traits you
-- define a struct based on michael_list::type_traits.

The forward iterator for Michael's list has some features:
- it has no post-increment operator
- to protect the value, the iterator contains a GC-specific guard + another guard is required locally for increment operator.
-- For some GC (gc::HP, gc::HRC), a guard is limited resource per thread, so an exception (or assertion) "no free guard"
-- may be thrown if a limit of guard count per thread is exceeded.
-- - The iterator cannot be moved across thread boundary since it contains GC's guard that is thread-private GC data.
-- - Iterator ensures thread-safety even if you delete the item that iterator points to. However, in case of concurrent
-- deleting operations it is no guarantee that you iterate all item in the list.
