Build a Molecule TODO
====================

Logging    (strippable)
Assertions (strippable)

Fix BucketFront colors - seems to be hue shifting
CollectionList/KitCollection - consider extending ObservableArray instead?

Check usages of getFirstTargetBox for handling undefined instead of null as a negative result

Memory:
  Atoms are storing too much info in their instances from their Element. It's convenient, but probably killing us.

Performance:
  ES5 getter/setter removal from inner-loop code

Specify sim title string for Sim

Common code for:
  HashMap
  Set

Preloader
Support portrait and landscape?
Full serialization?
Zoom/pan handler prototype
Recycling bin for molecules/atoms?
Handling hard-to-touch things:
  Scissors? - single-finger would interact with panning if zoomed in, might be acceptable
  3D button / break apart button - not sure

"Model":
  Tabs:
    Play area bounds
    Kit area bounds
    
    CollectionList:
      currentCollection
      
      KitCollections:
        currentKit
        
        Kits:
          Buckets:
            element
            atom ids
            position
          
        ColectionBoxes:
          moleculeType
          capacity
          quantity
          molecules
        
        Atoms:
          id
          element
          position
          destination
          userControlled
          visible
        
        Molecules:
          id
          cid
          atom ids
