Optimization. Faster.
Fixed typo introduced in last commit.
Removed old debugging comments in preparation for large refactoring.
More code cleanup. Consolidated duplicated code. Resulted in some good speedup.
Substantial simplification. Also resulted in speedup.
No longer using the BigInt library. Now the code manages its own array of bytes. Got a little bit of speed, but mostly it prepares us for further optimizations.
Fastest running time yet.
Added licensing instructions.
Added a TODO list.
Changed potentially dangerous strcpy() call to a safer strncpy() call.
Made the code more complaint with the Google coding guide.
