added states to mission manager. reformed simulator and delta clock so
that they better keep to their primary purposes. in other words the
simulator simulates, and the delta clock ticks.
added inputs and outputs to the roles in the team class. separated team
from the simulator. all team classes need customization in order to
simulate different teams. the simulator stands alone. the actors remains
as before, while all team classes remain throughout all simulations, the
actors may be completely deleted in some simulations.
