fetch-mock-forwarder is intended to be used as a "replacement" for isomorphic-fetch to be used by fetch-mock so that modules may still import isomorphic-fetch assuming that it has been aliased to this project.

This may be done in webpack as such:

resolve: {
    alias: {
        'isomorphic-fetch': 'fetch-mock-forwarder'
    }
}

In reality, all this package does is require whatwg-fetch and then calls the fetch function available on the global object.
