Add lots of style :sunglasses:
DRY the display logic

Makes functions for turning on and off info divs. Also uses pending,
fulfilled, and rejected styles for visual effect.
Lower number of objects

Seriously, 10000 objects is impressive but you'll never see it.
FYI: 100000 objects will make your browser :cry:
Add feature to allow rejected workers

Allow rejections in data_generator
