Library used to handle text selections. Selected text will return with contents, and rectangles for the region selected.
You can see how the library works by running
yarn build-test-app
This will build the app in /e2e/build_test_app/index.htm. This file will open a page with a basic usage of this library. You can also check /e2e/test_app/src/App.tsx for an example of how to implement the library.
