/**
* @ngdoc directive
* @name ui.router.state.directive:ui-sref
*
* @requires ui.router.state.$state
* @requires $timeout
*
* @restrict A
*
* @description
* A directive that binds a link (`<a>` tag) to a state. If the state has an associated
* URL, the directive will automatically generate & update the `href` attribute via
* the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
* the link will trigger a state transition with optional parameters.
*
* Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
* handled natively by the browser.
*
* You can also use relative state paths within ui-sref, just like the relative
* paths passed to `$state.go()`. You just need to be aware that the path is relative
* to the state that the link lives in, in other words the state that loaded the
* template containing the link.
*
* You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
* using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
* and `reload`.
*
* @example
* Here's an example of how you'd use ui-sref and how it would compile. If you have the
* following template:
* <pre>
* <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
*
* <ul>
* <li ng-repeat="contact in contacts">
* <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
* </li>
* </ul>
* </pre>
*
* Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
* <pre>
* <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
*
* <ul>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
* </li>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
* </li>
* <li ng-repeat="contact in contacts">
* <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
* </li>
* </ul>
*
* <a ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
* </pre>
*
* @param {string} ui-sref 'stateName' can be any valid absolute or relative state
* @param {Object} ui-sref-opts options to pass to {@link ui.router.state.$state#go $state.go()}

/**
* @ngdoc directive
* @name ui.router.state.directive:ui-sref-active
*
* @requires ui.router.state.$state
* @requires ui.router.state.$stateParams
* @requires $interpolate
*
* @restrict A
*
* @description
* A directive working alongside ui-sref to add classes to an element when the
* related ui-sref directive's state is active, and removing them when it is inactive.
* The primary use-case is to simplify the special appearance of navigation menus
* relying on `ui-sref`, by having the "active" state's menu button appear different,
* distinguishing it from the inactive menu items.
*
* ui-sref-active can live on the same element as ui-sref or on a parent element. The first
* ui-sref-active found at the same level or above the ui-sref will be used.
*
* Will activate when the ui-sref's target state or any child state is active. If you
* need to activate only when the ui-sref target state is active and *not* any of
* it's children, then you will use
* {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
*
* @example
* Given the following template:
* <pre>
* <ul>
* <li ui-sref-active="active" class="item">
* <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
* </li>
* </ul>
* </pre>
*
*
* When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
* the resulting HTML will appear as (note the 'active' class):
* <pre>
* <ul>
* <li ui-sref-active="active" class="item active">
* <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
* </li>
* </ul>
* </pre>
*
* The class name is interpolated **once** during the directives link time (any further changes to the
* interpolated value are ignored).
*
* Multiple classes may be specified in a space-separated format:
* <pre>
* <ul>
* <li ui-sref-active='class1 class2 class3'>
* <a ui-sref="app.user">link</a>
* </li>
* </ul>
* </pre>
