Some issues to make this compatible with React addon classSet about classnames

[chenglou]

I'm totally fine if you keep the current behaviour. I'll link to both https://github.com/petehunt/react-classset and this in the new React classSet readme.

Update: feel free to keep your current behaviour! I made that above repo fully backward compatible so that you don't have to =).

Thanks @chenglou

Passing null crashes it

Is this desired behaviour??

Empty class names return undefined rather than ''

Ditto

it'd be nice if this could be classNames camelCased

Do you mean camelCase the name of the package in npm?

[chenglou]

1. Nope.
2. Don't think so.
3. Don't think you can actually change it? In which case, nvm.

Made a new PR that fixes these ^
