* @public
* @function
* @param {object} options All options for the PayPalCheckout component.
* @param {string} options.flow Set to 'checkout' for one-time payment flow, or 'vault' for Vault flow. If 'vault' is used with a client token generated with a customer ID, the PayPal account will be added to that customer as a saved payment method.
* @param {string} [options.intent=authorize]
* Checkout flows only.
* * `authorize` - Submits the transaction for authorization but not settlement.
* * `sale` - Payment will be immediately submitted for settlement upon creating a transaction.

* @param {string} [options.currency] The currency code of the amount, such as 'USD'. Required when using the Checkout flow.
* @param {string} [options.displayName] The merchant name displayed inside of the PayPal lightbox; defaults to the company name on your Braintree account
* @param {string} [options.locale=en_US] Use this option to change the language, links, and terminology used in the PayPal flow. This locale will be used unless the buyer has set a preferred locale for their account. If an unsupported locale is supplied, a fallback locale (determined by buyer preference or browser data) will be used and no error will be thrown.
*
* Supported locales are:
* `da_DK`,
* `de_DE`,
* `en_AU`,
* `en_GB`,
* `en_US`,

* @param {string} [options.billingAgreementDescription] Use this option to set the description of the preapproved payment agreement visible to customers in their PayPal profile during Vault flows. Max 255 characters.
* @param {string} [options.landingPageType=login] Use this option to specify the PayPal page to display when a user lands on the PayPal site to complete the payment.
* * `login` - A PayPal account login page is used.
* * `billing` - A non-PayPal account landing page is used.
* @param {callback} [callback] The second argument is a PayPal `paymentId` or `billingToken` string, depending on whether `options.flow` is `checkout` or `vault`. This is also what is resolved by the promise if no callback is provided.
