Create a github-page static site.

The process of create a static site in the github-pages is simple, just create a branch called `gh-pages` with an index.html and, I think, the rest of the static files.

``` sh
# Creating the branch
$ git checkout -b gh-pages

# Adding all files of our static site
$ git add --all

# Committing your changes
$ git commit -m "fix #3 - Your commit message."

# Pushing the commits to our repository
$ git push origin gh-pages

# See the result
