title: insert a new document from querying combined collection
body: <p>I am new to Nosql world and meteor, I have two collections, taskCollectioin and workersCollection and my goal is to match each task to the available timeslot in workersCollection. my tasks collection has fields {client,task-name,time-flag,assigned=false} and my workers collection has field {name, timeslot:[slot, available]}. I have created also result collection called matchCollection result that need to insert a document resulting in matching of each task to available worker.</p>
  
  <p>My question: Since we are dealing with  querying from two different collection and comparing their field for matching, how would you implement a function in meteor that solves following psuedo code algorithm?</p>
  
  <pre><code>'FOR each task FROM TaskCollection
     | IF (assigned == false)
     |  |  get the task flag(for example: 10-12 pm)     
     | ENDIF   
     |  FOR each worker From collection
     |  |  **get worker slots
     |  |    IF (worker timeslot is availible for a given task time-flag)
     |  |    |   1-assign the task to the worker
     |  |    |   2-set the task assigned to true
     |  |    |   3-set the timeslot.available to false
     |  |    |   4-create a document in MatchCollection
     |  |    END IF 
     |  ENDFOR     
     ENDFOR'
  </code></pre>
