The widget is SVG, so this library fails for any browser that doesn't support svg.


### Potential Gradient Path Name Issue

I use the css property `fill: 'url(#starGrad<randomNum>)';` to fill in just a percentage of a star. It has some weird bugs depending on the pathname of the app. Normally SPA's have `window.location.pathname === '/'`, but if you append `window.location.origin` with the pathname of say `app`, so that `window.location.pathname === '/app/'`, then you need a gradientPathName of `'/app/'`.

Here is a stackoverflow post that I found that was related to this issue: http://stackoverflow.com/questions/36774188/svg-internal-url-links-and-iframes-on-wirecloud

## Contribute

If you want to contribute: Make changes in the src folder. And then run `make build`.
The `make build` command compiles react and es6 stuff using babel from `src/` into `build/`.
