Create recurring charge plan

Create a recurring charge plan. A recurring charge is a charge that is applied on a fixed schedule, such as an annual fee. When you create a recurring
charge plan, you specify the number of installments (cycles) and the installment amount. Creating a plan does not activate it. A plan must be linked to an
account to activate the charge schedule defined in it.
