===================
Bug Fixes
---------
* Resolving issue where subscription form would generate errors on
initial display.
* Fixed bug where ``PlanList`` would display ``SubscriptionPlan``
instances without associated `PlanCost` instances, resulting in
errors on subscription order preview.
Feature Updates
---------------
* Streamlining the ``PlanList`` - ``PlanListDetail`` -
``SubscriptionPlan`` relationship to make relationships more apparent
and easier to query.
* Added ``FactoryBoy`` factories to help streamline future test
writing.
* Added validation of ``PlanCost`` ``UUID`` in the
``SubscriptionPlanCostForm`` to confirm a valid UUID is provided and
return the object immediately.
* Updated ``PaymentForm to include validation of credit card numbers
and CVV numbers and switched expiry months and years to
``ChoiceField`` to ensure valid data collected.
