Modify cellsim-runner to run cell-sched.
Keep byte range requests within file size; closes #3
Make flowid_t a uint64_t since our hash is simply sport*dport for now.
Use pointers to allow late binding of enque() and deque()
Hopefully fixes #5
Fixed sfqCoDel bugs, I think this fixes #6
Allow cell-sched to take qdisc as argument.
Add qdisc to cellsim-runner.sh
Add deterministic random seed to on-off generator.
Refactor code to purge all global variables.

Log exceptions and requests to per-thread logs instead of stderr
