Grasping System

Builds on the trigger-based hand model that detects collisions with the
stimulus rod. Add to this a ‘halo’ around the center that guides the
subject to place the hand properly for the grasp. Does not yet include
the grasping motion itself.
Head Tilt / Flasher FSM template.

This was an attempt to help transfer some FSM states from one scene to
another. It is not entirely satisfactory because you still need to
connect all the objects. It would be good to find a better way.
Forced Choice tweak.

Some minor tweak to the forced choice paradigm. I’m not even sure what
it was.
Better Tilt/Flasher states into grasp.

I transferred the states from the Forced Choice paradigm to here.
Hopefully, I reconnected everything properly. This version of the
grasping hand based on dynamic finger movements works pretty well a lot
of the time, but it can get lost.
Initial version of trigger-based grasping paradigm.

Builds on the dynamics-based paradigm, using the trigger-based gripping
hand system that was developed in the collisions sandbox.
Organized objects into modules.

Created a number of modules composed of objects that are intertwined.
This should facilitate the create of prefabs that maintain the
interconnections.
Reorganization of keyboard actions.

<Shift> to rotate the head orientation.
<Ctrl> to move the hand.
<Alt><Ctrl> to rotate the hand.
Mouse can be used to move up, down, left, right and to rotate around
the roll axis.
‘L’ lowers the hand. ‘R’ raises the hand.
Adjusted gain on mouse rotations.
Added gripper opening and closing.
