Preliminary benchmark program uploads for SEDA-style response time percentiles vs requests / second
...
Also added a few cute little utilities:
- truncate_log
- run_recovery
Upped max # of concurrent transactions. (Current throughput during benchmarking remains ~flat up to 32,000
threads, but past max concurrent transactions was 1,000...)

new benchmarks revealed that inserts for linkedList, pageOrientedList were taking O(n) time, yielding O(n^2)
...
time to build a list, since the lists could not contain duplicate keys. These operations are now O(1), and
the lists can contain duplicates.
