"""Initializes the Data Flow Graph.
An evalContext is created to provide contextual information about the
evaluation to operators and other objects and systems with Fabric
Engine.
A binding to a graph is initialized and is setup so the application can
interact with it via the DFGWidget and through other scripted methods
within the application.
The UICmdHandler handles the interaction between the UI and the client.
The DFGWidget is the UI that reflects the binding to the graph that is
created and changed through the application.
