Conveyor Belt metaphor for Swarm's scheduling apparatus.
Time is a sequence of small links in a chain:
All Swarms that have been created in the program can "throw
actions" onto the belt when desired. When Swarms are created,
their "time scales" mesh because the actions they mandate fit
"onto" this chain at the appropriate time.
Swarm has standard terminology/structure to assure that:
a repeated action does in fact repeat
several actions thrown onto the belt at
the same time are handled "appropriately".
"Appropriately" means there are ways to
control the order in which actions at the same time are
executed. One may design simulations that randomize actions
that are in the same link of the the conveyor chain, or not.
