init() is called after all C++ SimObjects have been created and all ports are connected.
Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

startup() is the final initialization call before simulation.
All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.
