v0.2.0

Improvements:

• simplified internal logic
• extended options for OAuth and Rest

var oa = new OAuth2({
  config: {
    client_id: "",
    client_secret: "",
    project_key: ""
  },
  host: "auth.sphere.io", // optional
  accessTokenUrl: "/oauth/token" // optional,
  timeout: 20000, // optional
  rejectUnauthorized: true // optional
});

var rest = new Rest({
  config: {
    client_id: "",
    client_secret: "",
    project_key: ""
  },
  host: "api.sphere.io", // optional
  access_token: "", // optional (if not provided it will automatically retrieve an access_token)
  timeout: 20000, // optional
  rejectUnauthorized: true, // optional
  oauth_host: "auth.sphere.io" // optional (used when retrieving the access_token internally) 
});
