+//! `Hosts`: the main parent class that manages HostRegistry and HostContainer. It is also
+//!  responsible for filtering addresses before writing to the hostlist.
+//!
+//! `HostRegistry`: A locked HashMap that maps peer addresses onto mutually exclusive

+//!
+//! `HostContainer`: A wrapper for the hostlists. Each hostlist is represented by a `HostColor`,
+//!  which can be Grey, White, Gold or Black. Exposes a common interface for hostlist queries and

+//! > `Gold`: Hosts we have been able to establish a connection to in `OutboundSession`.

+//!
+//! > `Black`: hostile hosts that are strictly avoided for the duration of the program.
