===================
Feature Updates
---------------
* Added new functions to ``gateway`` module to:
* retrieve a user's saved Helcim tokens;
* retrieve details of a single Helcim token; and
* manage settings (this will verify that any required settings
declared and will provide defaults for all other settings as
appropriate).
* Extended the ``bridge_oscar`` module to:
* streamline validating a Helcim token for payment processing by
Django Oscar;
* handle whether a token should be associated with a ``django_user``
instance or a Helcim ``customer_code``; and
* provide convenience shortcut functions/dictionaries to
the ``bridge_oscar`` module to access functionality in
the ``gateway`` module.
* Updated the ``TO_API`` dictionary to remove ``order_number`` (not
recognized by the Helcim Commerce API).
* Updated sandbox site to demonstrate a workflow that makes use of the
Token Vault.
* Updated HelcimToken model to:
* record credit card type;
* display the "first 4 last 4" digits of the credit card number as a
16 character string; and
* retrieve and display an image for the corresponding credit card
type.
Bug Fixes
---------
* Fixed the ``refund`` and ``capture`` views to make use of the proper
settings (were still using the
outdated ``HELCIM_TRANSACTIONS_READ_ONLY`` setting).
