Adding Nick Palmer's submission;
* Memory mapped file, single-pass parsing, custom hash map, fixed thread pool
The threading was a hasty addition and needs work
* Used arraylist instead of treemap to reduce a little overhead
We only need it sorted for output, so only construct a treemap for output
* Attempt to speed up double conversion
* Cap core count for low-core systems
* Fix wrong exponent
* Accumulate measurement value in double, seems marginally faster
