Stall analytics

Allow the stall managers to view basic analytics about stall traffic

I'm considering what the best metrics to present would be here. Open questions here:

• What do stallholders want to know?
• Which metrics are actually meaningful? (i.e. there is little point presenting information that is misleading / worthless, even if people are asking for it)

The most foolproof method here might be to present quite low-level data, e.g. "person with pseudonymous identifier 238764 entered stall at 12:37 and stayed until 12:43" to let socs do whatever processing they want on it. Caution privacy considerations!

Do we perhaps want to graph the number of users with time? I believe the BBB webhooks could be used for this, or we could poll the server for the user count periodically.

Is this actually useful though, given that it's probable that moderator(s) / committee members will probably be present anyway and be able to see this information first-hand?
