      Decorator to switch an url from http to https.
  
      If a view is accessed through http and this decorator is applied 
      to that view, than it will return a permanent redirect to the 
      secure (https) version of the same view.
  
      The decorator also must check that ``ACCOUNTS_USE_HTTPS`` is enabled. 
      If disabled, it should not redirect to https because the project 
      doesn't support it.
