Better documentation for setupTests.js when ejecting 
When running `npm run eject` before creating `src/setupTests.js`, the resulting `package.json` file, won't contain any entry for it - and this is correct in my opinion, since otherwise Jest will crash - but it's useful to have it documented and avoid pointless waste of time.

>Note: Please keep in mind that, if you decide to `npm run eject` before creating `src/setupTests.js`, the resulting package.json file won't contain any reference to it, so you should manually create the property `setupTestFrameworkScriptFile` in the configuration for Jest, something like the following:
>```
>"jest": {
> ...
> "setupFiles": [
> "<rootDir>/config/polyfills.js"
> ],
> "setupTestFrameworkScriptFile": "<rootDir>/src/setupTests.js",
> ...
> }

### Focusing and Excluding Tests

You can replace `it()` with `xit()` to temporarily exclude a test from being executed.<br>
