/**
* `HashLocationStrategy` is a {@link LocationStrategy} used to configure the
* {@link Location} service to represent its state in the
* [hash fragment](https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax)
* of the browser's URL.
*
* For instance, if you call `location.go('/foo')`, the browser's URL will become
* `example.com#/foo`.
*
* ### Example
*
* ```
* import {Component, provide} from 'angular2/core';
* import {
* Location,
* LocationStrategy,
* HashLocationStrategy
* } from 'angular2/platform/common';
* import {
* ROUTER_DIRECTIVES,
* ROUTER_PROVIDERS,
* RouteConfig
* } from 'angular2/router';
*
* @Component({directives: [ROUTER_DIRECTIVES]})
* @RouteConfig([
* {...},
* ])
* class AppCmp {
* constructor(location: Location) {
* location.go('/foo');
* }
* }
*
* bootstrap(AppCmp, [
* ROUTER_PROVIDERS,
* provide(LocationStrategy, {useClass: HashLocationStrategy})
* ]);
