// Here is an extremely simple version of work scheduling for multiple
// processors.
//
// The Problem: 
//  We have a lot of numbers that need to be math'ed. Doing this on one 
//  CPU core is slow. We have 4 CPU cores. We would thus like to use those
//  cores to do math, because it will be a little less slow (ideally
//  4 times faster actually).
//
// The Solution:

git checkout --orphan future-master
git add -A  # Add all files and commit them
git commit
git branch -D master  # Deletes the master branch
git branch -m master  # Rename the current branch to master
git push -f origin master  # Force push master branch to github
git gc --aggressive --prune=all     # remove the old files
