   Plans specify the terms of a subscription contract. Each Plan has a name and refers to the purchase of a single product. The details of a Plan are arranged by phase.
   In the illustration above we are showing a Plan with a 30 day Trial followed by an unlimited recurring or "evergreen" phase.

   For each phase of the Plan we need to specify:
   
   * Phase Type - can be one of TRIAL, DISCOUNT, FIXEDTERM, EVERGREEN
