class_docstr: Tuple-valued parameter. This Parameter can contain other Parameters,
  its value is tuple which values are either directly the provided values
  if they are not Parameter instances, or the value of those Parameters.
  It also implements a getter to access the Parameters directly if need be.
  
  Parameters
  ----------
  **parameters: Any
      the objects or Parameter which will provide values for the tuple
  
  Note
  ----
  This is the base structure for all container Parameters, and it is
  used to hold the subparameters for all Parameter classes.
