 * @static
 * @function create
 * @param {object} options Creation options:
 * @param {Client} [options.client] A {@link Client} instance.
 * @param {string} [options.authorization] A tokenizationKey or clientToken. Can be used in place of `options.client`.
 * @param {boolean} [options.debug] A debug flag.
 * @param {string} [options.redirectUrl] When provided, triggers full page redirect flow instead of popup flow.
 * @param {callback} [callback] When provided, will be used instead of a promise. First argument is an error object, where the second is an instance of {@link SEPA|SEPA}.
 * @returns {Promise<void|error>} Returns the SEPA instance.
 * @example
 * braintree.sepa.create({
 *   client: clientInstance
 * }).then(function (sepaInstance) {
 *   // sepaInstance is ready to be used.
 * }).catch(function (createErr) {
 *   console.error('Error creating SEPA instance', createErr);
 * });
 * @example <caption>Creating a SEPA component</caption>
 * braintree.sepa.create({

 *   // sepaInstance is ready to be used.
