Sequence diagram for Assign Employee feature in DG

[aliciatay-zls]

(pg 7 of DG)

• missing return arrows for self-invocations
• missing return arrow at the end
• typo "shifts is not empty"
• typo "Alt" far left
• wrong format for "alt" box (condition should be beside the "alt" tag, looks like it is part of the method call)
• heavily nested (multiple "opt" boxes)
• could be broken up into a few diagrams and explained with their respective description paragraphs so that it is not such a long chunk of steps (pg 6)
