Add a user statistics page to Caesar's web UI?

[ramanakumars]

Is it possible to add a user statistics page, similar to the current subject statistics page (see screenshot), that shows which workflows the user is assigned to, how many classifications they have in each workflow, and which subjects they have classified? Maybe under /projects/[project-id]/users/[user-id]?
