'''

Author:  Steven K. Pollack
Date Released: May 16, 2015

allow for text editing to encapsulate specific views from a pyui as subviews of a "container" view

The strucure of a "node" is a dictionary with the four keys:

{ "attributes": {dictionary of artibutes of the current node},
  "frame" : "{(top,left},{width,height}}", # notes this is not a dictionary
  "nodes": [list of subviews], # a subview is a node
  "class": "class type"
}

The topmost node (the rootView) is a list with a single node
