  /* \brief Indexing operator.
 
  This is the indexing operator used to extract an ensemble member
  with a (simpler) construct like x=e[i] as opposed to x=e.member[i].
  The later is possible because we (intionally) make the member Container
  public, but this operator can be used to write code that follows common
  guidelines to not make data public.   It will be used for the python
  interface.
 
  \param n  is the member to be extracted and returned.
