What problem would you like to solve? Please describe:
Confidence when making changes to a temporary schedule

Describe the solution you'd like:
Add a diff feature to track changes in shifts. Changes include added or removed shifts, and added or removed users.

Describe alternatives you've considered:
Diffing via JSON serialization was touched on during a meeting.

Additional context:

1. User adds all shifts to temp sched, wants to finish & create
2. User clicks Submit
3. Dialog transitions to new screen, old (current) shift set on the left, new shift set on the right.

• Shifts should line up one-to-one so differences are easily identifiable.
• Shifts that are the same can be dimmed?
• Shifts that are different can be accentuated?
