Time and Weather based Affordances should update more frequently

[youralien]

The whole system currently runs on an event-based model, upon a user's location change.

However, there are cases where situations are changing despite a static location. For example, the weather can change to rainy, despite a user being in the same location. Or time continues to progress, despite a user being in the same location.

This illustrates a new model, where the event-based onLocationUpdate model is compatible with a more frequent polling-based onTimeElasped model.

To implement this, I would do the following tasks

• Make the processes for "coordinating users to needs" in a separate function. Currently it occurs in the callback of getAffordancesFromLocation:

  ce-platform/imports/api/UserMonitor/locations/methods.js

  Line 72 in 06b206a

  getAffordancesFromLocation(uid, location, retrievePlaces, function (uid, bgLocationObject, affordances) {

  ,
• Create a polling function on the server side onTimeElasped, perhaps on a 5 minute interval. Use functions like setInterval. Perhaps, it could iterate through all users in db.Locations
• Then make sure "coordinating users to needs" is called for the onLocationUpdate and the onTimeElapsed models (see

  ce-platform/imports/api/UserMonitor/locations/methods.js

  Line 107 in 06b206a

  decomissionFromAssignmentsIfAppropriate(uid, sharedAffs);

  )
