PayPal ExpressCheckout for WordPress

Usage:

1. Declare an array with all the required parameters.
2. Create a new instance of the class. Set the second parameter to true if you want to enable SandBox mode.
3. Get the redirect URL with the doExpressCheckout function.
4. Redirect the user to that URL to request permission.
5. Use the processPayment function to process the payment.

Update: please note that I have since switched to using a set of bash scripts instead of poluting the Git repository with git svn.
