* @description
* A {@link LocationStrategy} used to configure the {@link Location} service to
* represent its state in the
* [path](https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax) of the
* browser's URL.
*
* If you're using `PathLocationStrategy`, you must provide a {@link APP_BASE_HREF}
* or add a `<base href>` element to the document.
*
* For instance, if you provide an `APP_BASE_HREF` of `'/my/app/'` and call
* `location.go('/foo')`, the browser's URL will become
* `example.com/my/app/foo`. To ensure all relative URIs resolve correctly,
* the `<base href>` and/or `APP_BASE_HREF` should end with a `/`.
*
* Similarly, if you add `<base href='/my/app/'/>` to the document and call
* `location.go('/foo')`, the browser's URL will become
* `example.com/my/app/foo`.
*
* Note that when using `PathLocationStrategy`, neither the query nor
* the fragment in the `<base href>` will be preserved, as outlined
* by the [RFC](https://tools.ietf.org/html/rfc3986#section-5.2.2).
*
