Started fleshing out what we want for our properties for tracking changes
Linking of a readModelOf to Command starting come together.
Command now extends with for now an unknown extension types; hasChanges
Final stretch - started getting the isReady and hasChanges in place
Adding more specs
hasChanges observable extension in place
Adding function for populating from an external source - that way we keep the right state all the time for isReady and hasChanges
hasChanges up and running for command!
Merge branch 'CommandHasChanges'
