title: Remove filtered out elements from ArrayCollection in ActionScript3
body: <p>I have a big ArrayCollection variable.
  I want to filter it several times and each time assign the filtered result to a different ArrayCollection variable.</p>
  
  <p>So if it has let's say people, fruits and cars. (for illustration purposes)
  I want to first filter it to only show people, assign the result to a people ArrayCollection, then filter it to show fruits and assign it to a fruits ArrayCollection and so on.</p>
  
  <p>How can I do that? Not the filtering, but the assignment after filtering.
  Or is it faster to instead run a for-loop through the big ArrayCollection and just add each item into the corresponding smaller ArrayCollection?</p>
