My own solution -- memory mapping the files, running in parallel threads, using a state machine to parse the file (#466)
* Golang implementation
* Speed up by avoiding copying the lines
* Memory mapping
* Add script for testing
* Now passing most of the tests
* Refactor to composed method
* Now using integer math throughout
* Now using a state machine for parsing!
* Refactoring state names
* Enabling profiling
* Running in parallel!
* Fully parallel!
* Refactor
* Improve type safety of methods
* The rounding problem is due to difference between Javas and Gos printf implementation
* Converting my solution to Java
* Merging results
* Splitting the file in several buffers
* Made it parallel!
* Removed test file
* Removed go implementation
* Removed unused files
* Add header to .sh file
