Entanglement centers with qubits

- Paused creating the matrices to talk to Seth and figure out
what to do about qubits needing to be off center when there
is an odd number of them.
- For now, using yOffset to offset the entanglement visual too.
There's no animation of the entanglement, so I can't see if that
movement will show when the visualization actually transitions
positions.
Paused to fix chord opacity, fixed now.

- Noticed that mousing over chord diagram made self-referential (?)
paths appear. That should be fixed now. Was working on getting
matrix data into each qubit.
