Add an option to cancel and/or reschedule an existing event
Slightly increse test coverage of simulation.py
Simulation: split _process_event into multiple handler methods
Node: _copy_replica now raises an error if copying an existing replica
Node: fix logic when node already has a specific replica when it receives it
Fix some assertions in test_lt_compares_by_id
Inter-arrival times for node's replica requests are now global for the network
Event: fix __lt__ comparison to canceled events
Node's bandwidth is now split between replicas being concurrently sent
