+//! The statement table.
+//!
+//! This stores messages other authorities issue about candidates.
+//!
+//! These messages are used to create a proposal submitted to a BFT consensus process.
+//!
+//! Proposals are formed of sets of candidates which have the requisite number of
+//! validity and availability votes.
+//!
+//! Each teyrchain is associated with two sets of authorities: those which can
+//! propose and attest to validity of candidates, and those who can only attest
+//! to availability.
