Added carousel example with README
gh-pages

commit 72a5abad37

This carousel example uses `style transform` and `transition` to rotate a group of SVG triangles.
Also, the color of each triangle changes when you hover or click/tap it.
I built the build.js using npm and browserify.
In my local copy of the snabbdom project root I did these preparations:
```
npm install --save-dev babelify
npm install --save-dev babel-preset-es2015
echo '{ "presets": ["es2015"] }' > .babelrc
```
I then built like this:
```
browserify examples/carousel-svg/script.js -t babelify -o examples/carousel-svg/build.js
```
