potential api example

bit fix undo-commit
bit fix untrack-file
bit fix rename-commit
bit fix catch-up-to-branch

Right now query in the nodejs api is just a string. we should support gql-parsed strings too, so that if they are exported elsewhere, it can be used directly.

import gql from 'graphql-tag';

export const GRAPHQL_QUERY=gql`
  query {
    something {
      anotherthing
    }
  }
`;

Suggestion

Add a section to the README about how to test this component.

Motivation

I've come across countless issues and questions in the gitter about how to test or mock this library. If anyone has done this before, please consider adding a testing guide to the README.
