Merge branch 'dev' of github.com:DistributedObjectProtocol/dop

* 'dev' of github.com:DistributedObjectProtocol/dop:
  Improved observer object and remove dop.observe from the API
  Changed the system of observers based absolute paths instead of storing inside of the object
  We update computed values after each recalculation to observe new derivations
  Only one array of collectors instead of two
  Merging observe and observeProperty with createObserver
  Fixeds some problematic cases in computed values
  Making computed/derived properties
