//! The `drone` module provides an object for launching a Solana Drone,
//! which is the custodian of any remaining tokens in a mint.
//! The Solana Drone builds and send airdrop transactions,
//! checking requests against a request cap for a given time time_slice
//! and (to come) an IP rate limit.
