====== PayPal ======
The PayPal field allows a software developer to show a button that initiates a PayPal Express Checkout payment session.  Options are available to define a single line item to pay for with Pay Pal inside the PayPal pages in a popup window.  PayPal's page that will open defaults to the "no PayPal account" option so credit card information can be provided.  It is still possible for the end user to pay with their PayPal account if they so choose, and only instant payment methods will be accepted.
