// Notes
// Change the upper bound the of loop from 100 to anything you like, depending upon the total number of commits of the repo
// If your internet speed is slow, change 2000 to something higher like 4000 or something...
// This code may become obsolete in the future if GitHub changes there HTML code, so contributions are always welcome :)
// Enjoy!
