Context

The use should be able to track the progress of the tool, or at minimum know the tool is running.
It will allow users to track the progress of the tool.

Possible Implementation

Grey out the Start Fair Assessment button when clicked, possible with CSS / JS / Bootstrap toggle states. Add a progress bar, incrementing with each marker, possibly using the Bootstrap progress bar.
