2.0.0: new version of the SDK

• Users can now authorize future payments with PayPal.
• Reorganize API, for both single-payment and future-payment use cases:
  • Use the PayPalMobile class to initialize the SDK with Client IDs for Production and Sandbox.
  • Use a PayPalConfiguration object for common configuration across both single-payment and future-payment use cases.
  • Allow an optional PayPalPaymentDetails object to specify Shipping, Subtotal, and Tax amounts.
  • Allow an optional Build Notation code ("BN code") for each payment.
  • Add a PayPalPaymentViewController parameter to the methods of PayPalPaymentDelegate.
  • Introduce PayPalFuturePaymentViewController and associated PayPalFuturePaymentDelegate.
• Single payments now include an intent property, to distinguish between:
  1. immediate payment processing
  2. payment authorization only, with subsequent capture by your server.
• For API errors, the console log will now provide additional information, including a PayPal Debug-ID for MTS investigations.
• The SDK now uses PayPal's new REST APIs exclusively.
