"Scratch Art" with new Edge Detection ARCore Depth API Template

Thought I would experiment with the new Depth Materials Template. When available, the depth templates can use depth data provided by Google’s ARCore Depth API to enhance the Lens experience--whether it be to occlude content by physical objects, get information about surfaces in the camera, or to create effects that respond to depth.  

Goal:

Take the Depth Materials Template and configure the "Edge Detection" example to change color with the UI Control Template to create an effect similar to "Sketch Art".

Build Notes:

1. Downloaded new Depth Materials Template.
2. Enabled the Edge Detection Example
3. Added an Orthographic Camera by adding a screen image.
4. Imported the UI Control Template and placed under the orthographic camera.
5. Disabled all controls other than the UI Color Picker
6. Setup the Scene Config and layers so that the UI toggle wouldn't appear in the Snap that was captured.
7. Inspected the Edge Detection material to see which parameter needed to have the color input. Script Name "lineColor"
8. Modified the UIColorPicker script to add the output of the color picker to the material.
9. First added this line to be able to select the material.
10. Next added a line to the updateColorVisual Function
