Add a way to run vue-tree-table locally without having to install dependencies

[gui-ben]

Hi! Vue-tree-table looks very cool!

I would like to play with it, but I don't have the dependencies installed. I cloned the repo but couldn't load index.html because I don't have the dependencies.

I was able to run vue-tree-table from /dist/vue-tree-table, but that is the minified version of the page. So that wasn't useful.

Could you add to the repo a directory with the unminified version of all the components, so we can run it locally without having to install dependencies? Just like one can run online a component in jsfiddle.net.

I could help translating the repo to English if needed, so it can be more popular!

Thanks.
