Value Ladder

A high precision number selector I found in Houdini VFX, ported to 3D for AR/VR.

TO-DO:

1. Animate opening and closing for compactness when not in use.
2. Allow user the shortcut of clicking on number line, instead of dragging the corresponding cube.

ANIMATION PLAN:
Deploy ladder from the number output container.

1. Interact with output display
2. Ladder deploys vertically
3. Hover over a magnitude
4. Magnitude deploys horizontally.
5. Magnitude collapses horizontally when focus is lost.
6. Ladder collapses vertically when focus is lost.
