This adapter adds an integration with the Navigation API, allowing
SPA Router navigations to be displayed more fully in the browser UI.
With this, site visitors will be able to see that a page is loading via
the loading spinner in the tab. They will also have access to cancel the
navigation with the browser UI via the "stop" button or by pressing the
escape key (only relevant for slower connections).

To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.
