HOW IT WORKS
------------
* Checkout redirection
  When an anonymous user tries to access the checkout will be redirect to
  the default login page or custom path if was set in the module configuration,
  If set a message could be displayed to the user.
  There are several posibilities for the user:
  - User login
  - Continue as anonymous
  - Register
  - Request password
* Back to checkout
  Based on the options from above the user will be redirect back
  to the checkout page.
  There is an extra step when the user needs to check the email for
  the reset password link, for Request password and Register with administrator approval
  or e-mail verification.
