49//! The scheduler is designed for deferred transaction calls by block number.
50//! Any user can book a call of a certain transaction to a specific block number.
51//! Also possible to book a call with a certain frequency.
52//! Key differences from original pallet:
53//! Id restricted by 16 bytes
54//! Priority limited by HARD DEADLINE (<= 63). Calls over maximum weight don't include to block
55//! Maybe_periodic limit is 100 calls
56//! Any account allowed to schedule any calls. Account withdraw implemented through default transaction logic.
