//! Common lockchain error handling
//!
//! `Error` is a wrapper type around many different errors
//! that are provided by different parts of
//! the `lockchain-core` crate.
//!
//! It also re-exports those error types so that a user can use
//! the error handling module simply by including `lockchain_core::errors::*`
