Explicit demonstration page

[koppor]

After inclusion of the README.md as homepage (http://ultimate-comparisons.github.io/ultimate-comparison-BASE/), the possibility to provide a demonstration was lost.

I can point to a PR (.g., http://ultimate-comparisons.github.io/ultimate-comparison-BASE/prs/rewrite/) in the README md, but what if the PR is lost?

I see following alternatives:

• build all tags and offer it as sub-directory at gh-pages
• Always build the master branch and offer it as sub-directory at gh-pages
• Create a demo branch and offer it as sub-directory at gh-pages

I opt for the first one as this follows the inspiration of tags and the master branch could be broken sometimes.

It can be found under https://ultimate-comparisons.github.io/ultimate-comparison-BASE/demo/. I will add a point in the index.md.
