-//! High level lightning structs and impls live here.
-//!
-//! You probably want to create a channelmanager::ChannelManager, and a routing::NetGraphMsgHandler first.
-//! Then, you probably want to pass them both on to a peer_handler::PeerManager and use that to
-//! create/manage connections and call get_and_clear_pending_events after each action, handling
-//! them appropriately.
-//!
-//! When you want to open/close a channel or send a payment, call into your ChannelManager and when
-//! you want to learn things about the network topology (eg get a route for sending a payment),
-//! call into your NetGraphMsgHandler.
