[kepler-dev] validateSettables in Manager

[Edward A. Lee]

I see...

I see two alternatives:

  1) Extend TypedAtomicActor, but implement an empty fire() method
     and a postfire() method that returns false.  Then only one firing
     will be reported.

  2) Since you are listening to the director, perform initialization
     when the director reports it is initializing.
