tokenburn-core 0.1.4

//! Refresh benchmark: how long does re-reading your logs take, cold and warm?
//!
//!     cargo run --release -p tokenburn-core --example bench            # this month
//!     cargo run --release -p tokenburn-core --example bench -- all     # all history
//!     cargo run --release -p tokenburn-core --example bench -- all 10   # …10 refreshes
//!
//! The first run is "cold" (every file parsed); later runs show what an
//! auto-refresh costs when little has changed.
