+ *

+ *          $p->add_field('business', 'somebody@domain.com');
+ *          $p->add_field('first_name', $_POST['first_name']);
+ *          ... (add all your fields in the same manor)
+ *          $p->submit_bitpay_post();
+ *
+ *      To process an IPN, have your IPN processing file contain:
+ *
+ *          $p = new bitpay_class;
+ *          if ($p->validate_ipn()) {
+ *          ... (IPN is verified.  Details are in the ipn_data() array)
