# Recursive backtracking algorithm for maze generation. Requires that

# learn and implement, and (with a few tweaks) gives fairly good mazes.
# Can also be customized in a variety of ways.

Countdown.js is a simple script to add a countdown timer

and partial minutes aren't supported. This script is a fork of http://jsfiddle.net/HRrYG/ with some 
added extensions. Since the original code that I forked was released under Creative Commons by SA license,

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

• Example: https://gist.github.com/atenni/5604522/raw/
• Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]
