//! Relaying source chain headers to target chain. This module provides entrypoint
//! that starts reading new headers from source chain and submit these headers as
//! module/contract transactions to the target chain. Module/contract on the target
//! chain is a light-client of the source chain. All other trustless bridge
//! applications are built using this light-client, so running headers-relay is
//! essential for running all other bridge applications.
