  A user's presence is the recent status of that user. Each updated presence lasts for 15 minutes, or until another
  status is given. Users who do not have a current status show up as "offline".

  A user's status can be updated on any authenticated call by simply including the update_presence query parameter
  with a status for its value. If this method is attempted, the response's meta.updated_presence key will be set and
  true. If it fails to update, it will be false.

  Endpoints:
  - Get present users
  - Get a user's presence
  - Update the authenticated user's presence
