Starts attempts to visualize entanglement

Starting with d3 chord diagram
Adds some functions, but doesn't affect page yet
Things are appearing, in many ways appearing wrong

What up with the odd number of qubits not being centered?
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.
Right number of sections, wrong rotation
Colors are weird, but it should be rotating correctly now
Trying new way of creating the matrix

- Trying to use d3 data instead of jQuery data
New matrix seems to be working

Wait, why am I doing this, the data has to be set in qromp.js
anyway.
Gets it working again. Issue - clicking too fast creates problems.
Left over circle problems gone, timing off

- Also now there are a ton of errors, not sure why values aren't
getting assigned.
Merge pull request #16 from knod/entang

Entang - places d3 chord diagram with colors for identification atm
