-//! The `plan` module provides a domain-specific language for payment plans. Users create BudgetExpr objects that
-//! are given to an interpreter. The interpreter listens for `Witness` transactions,
-//! which it uses to reduce the payment plan. When the plan is reduced to a
-//! `Payment`, the payment is executed.
