TODO/Notes

• Unify the observer code for use in MRML, Logic, and GUI
  • currently there is much duplication of the command callback structures
  • perhaps this needs to be a separate library that can be used by all?
  • we should be specifically observing DeleteEvent to avoid observing events invoked during destructors
  • The SetAndObserve* calls should also have a signature where they accept an event to observe
  • Perhaps this layer could also allow us to disable all the callbacks (not clear this is needed)
