part I of revised approach to commands/projects 

no privileged project member of State
no separation of Command and Apply, so no pre-filtering on State
use entries in State attributes map instead of mixing in traits to project object:
  HistoryPath, Logger, Analysis, Navigate, Watch, TaskedKey
rework Navigation to be standalone instead of mixin
