class_docstr: Make blob objects behave like Python strings.
  
  Expects that classes that use this mixin to have a _strkey() method that
  returns the string to apply string methods to. Using _strkey() instead
  of __str__ ensures consistent behavior between Python 2 and 3.
docstr: Returns a string representation used in print statements
  or str(my_blob).
