Create receipt for a payment.

Create a receipt for a payment and optionally specify allocations per transaction. In case of no allocations, a 'Simple receipt' will be created that can later be allocated to charge transactions. The amounts of all allocations must be equal to the payment amount. The transactions should not be fully allocated already and the amount allocated should not be more than the remaining balance on the transaction. All transactions not part of an invoice will be added to newly created invoice.
