class_docstr: Mark a function, class, or method as deprecated (decorator).
  
  Originally adapted from sklearn and
  http://wiki.python.org/moin/PythonDecoratorLibrary, then modified to make
  arguments populate properly following our verbose decorator methods based
  on decorator.
  
  Parameters
  ----------
  extra : str
      Extra information beyond just saying the class/function/method is
      deprecated. Should be a complete sentence (trailing period will be
      added automatically). Will be included in FutureWarning messages
      and in a sphinx warning box in the docstring.
