Making google variable accessible

[ynnelson]

Need to make google accessible in order to call google.picker.Action.PICKED or other variables from my components using the hook.

It makes writing callback function like the one below easier.

callbackFunction: (data) => {
        let url = "";
        if (
          data[google.picker.Response.ACTION] === google.picker.Action.PICKED
        ) {
          let doc = data[google.picker.Response.DOCUMENTS][0];
          url = doc[google.picker.Document.URL];
        }
      }
