Improve documentation

[YerkoPalma]

Hi, thanks for this repo, is really useful and well done. However, I think that the docs can be improved a lot. It happens to me that when I have a specific issue with vue-resource I have to dig into the issues and pull requests to find an answer, so I suggest to improve documentation, by creating a gh-pages branch, and using gitbook like vue-router and vuex does.

What I would add to existing documentation

• A litle bit about CORS usage
• Examples and reference of file transfer
• Better examples of interceptors usage
• A whole topic about testing
• And maybe a FAQ section with the most repeated issues?

thanks for readings 😄

@YerkoPalma Thanks for your suggestions. Currently all documentation files are in /docs in folder. If you like help me out on a topic you suggested, please send me a pull request. Gitbook looks nice, i will try to move the current docs to gh-pages.

I don't know if you have already submitted a PR. But the finally clause is a good thing to document. Although it's part of native JS, the changes on the API compared to the native fetch may make someone else confused.
