class_docstr: A pen that creates a CGPath
  
  Parameters
  - path: an optional CGPath to add to
  - xform: an optional CGAffineTransform to apply to the path
code: def __init__(self, glyphSet, path=None, xform=None):
      BasePen.__init__(self, glyphSet)
      if path is None:
          path = CGPathCreateMutable()
      self.path = path
      self.xform = xform
