class_docstr: A residual connection followed by a layer norm.
  Note for code simplicity the norm is first as opposed to last.
code: def __init__(self, size, dropout):
      super(SubLayerConnection, self).__init__()
      self.norm = nn.LayerNorm(size)
      self.dropout = nn.Dropout(dropout)

label_desc: Use image node_id 1 to create a new SubLayerConnection object from inherited base classes: nn with example: obj = SubLayerConnection(size, dropout)
