Example of interacting with uFrame from NodeCanvas

AttackAction.cs

using System.Collections.Generic;
using NodeCanvas;
using NodeCanvas.Variables;
using UnityEngine;

/*
Let us assume you have a uFrame Entity which can attack
and when it does it needs to play an animation in the view layer
and also needs to tell the controller to trigger an attack
in the back end. An attack may not hit anything but we would
delegate that call to the Controller to deal with

We can assume that the View has a ViewComponent for dealing
with animations and another for dealing with effects, 
and has a controller for dealing with the actual hit logic.
