class_docstr: Class for Hermitian spaces.
  
  By definition, a Hermitian space is a complex vector space
  of a given dimension, equipped with a Hermitian metric.
  
  Parameters
  ----------
  dim : int
      Dimension of the Hermitian space.
docstr: Identity of the group.
  
  Returns
  -------
  identity : array-like, shape=[n]
