//! Payment Intent
//! ==============
//!
//! Reference: <https://stripe.com/docs/api/payment_intents>
//!
//! This example shows how to creeate a [PaymentIntent] and use it to create a
//! charge for a fictional card. We create a customer, an intent, update
//! their payment information, and lastly use the intent to create a charge.
