StringCalculatorPage.new() works well, but I realized two things:
- I could autogenerate app element IDs using monotonically increasing
numbers, eliminating the need for an appElemId argument.
- Creating and destroying a new <div> for every test case seemed to
start slowing the tests down.
Now the guidance isn't to call StringCalculatorPage.cleanup() in
afterEach, but to use the pattern:
```js
describe('initial state after calling initApp', () => {
const page = StringCalculatorPage.new()
afterEach(() => page.clear())
afterAll(() => page.remove())
```
