The main class is thesession, it contains the main loop that serves all torrents.The basic usage is as follows:construct a sessionload session state from settings file (seeload_state() save_state()start extensions (seeadd_extension().start DHT, LSD, UPnP, NAT-PMP etc (seestart_dht() stop_dht() set_dht_settings() dht_state() is_dht_running()start_lsd() stop_lsd(),start_upnp() stop_upnp()andstart_natpmp() stop_natpmp()parse .torrent-files and add them to the session (seebdecode() bencode()andasync_add_torrent() add_torrent(),API Overview,main loop (seesession)query the torrent_handles for progress (seetorrent_handle)query the session for informationadd and remove torrents from the session at run-timesave resume data for all torrent_handles (optional, seesave_resume_data()save session state (seeload_state() save_state()destruct session objectEach class and function is des,Details,参考使用手册,Libtorrent代码分析,线程模型,主线程：Session线程，处理设置，查询等业务文件线程：disk_io_thread.网络线程：io_service，定义如下：typedef boost:asio:io_service io_service;在windows平台上通过完成端口实现,线程模型,typedef boost:asio:io_service,线程模型,disk_io_thread与chrome的线程模
