* reshuffle consensus libraries * polkadot-useful type definitions for statement table * begin BftService * primary selection logic * bft service implementation without I/O * extract out `BlockImport` trait * allow bft primitives to compile on wasm * Block builder (substrate) * take polkadot-consensus down to the core. * test for preemption * fix test build * Fix wasm build * Bulid on any block * Test for block builder. * Block import tests for client. * Tidy ups * clean up block builder instantiation * justification verification logic * JustifiedHeader and import * Propert block generation for tests * network and tablerouter trait * use statement import to drive creation of further statements * Fixed rpc tests * custom error type for consensus * create proposer * asynchronous proposal evaluation * inherent transactions in polkadot runtime * fix tests to match real polkadot block constraints * implicitly generate inherent functions * add inherent transaction functionality to block body * block builder logic for polkadot * some tests for the polkadot API
