cleanup and notes
Fix benchmarks for criterion 1.0
move constants to bottom of file
tweaks for looking at core
Bump atomic-primops version so we can use GHC 7.8.3. Fixes #9. Thanks, abbradar
Share constants and hard-code lOG_SEGMENT_LENGTH, which gives us ~7% speedup in single-threaded test of boxed Unagi. Experiments hard-coding other literals didn't give any interesting results. Fixes #5. Thanks to kvanberendonck for encouraging me to investigate. Bump version.
