               OutputNode

base class for nodes which dump output

Assumptions:

  - destination supports a write() method

  - strFunc, if provided, returns a string representation of
    the input

  - inputs (parents) can be stepped through in lockstep


Usage Example:
  >>> from rdkit.VLib.Supply import SupplyNode
  >>> supplier = SupplyNode(contents=[1,2,3])
  >>> from rdkit.six import StringIO
  >>> sio = StringIO()
  >>> node = OutputNode(dest=sio,strFunc=lambda x:'%s '%(str(x)))
  >>> node.AddParent(supplier)
  >>> node.next()
  1
  >>> sio.getvalue()
  '1 '
  >>> node.next()
  2
  >>> sio.getvalue()
  '1 2 '

x.__init__(...) initializes x; see help(type(x)) for signature
