Suggest Course Links #593

I am exploring MongoDB aggregations and turns out its exactly what we need for crowd-sourcing data.

We can use this aggregation to get all links for each (or a single) course:

[
  {
    '$match': {}
  }, {
    '$unwind': {
      'path': '$links', 
      'preserveNullAndEmptyArrays': false
    }
  }, {
    '$group': {
      '_id': '$summary', 
      'links': {
        '$addToSet': '$links'
      }
    }
  }
]

We can use this to suggest links for users when they add their courses.
