change log v1.1.0

No longer inject axios in resource-axios's src, let you do the work in your project codes, in this way keeping axio isolated and can be up to date.

Before v1.1.0:

import resource from 'resource-axios';

const Book = resource('/api/books');

Since v1.1.0:

import resource from 'resource-axios';
import axios from 'axios';

const Book = resource('/api/books', axios);
