/**
* `ui-view`: A viewport directive which is filled in by a view from the active state.
*
* ### Attributes
*
* - `name`: (Optional) A view name.
* The name should be unique amongst the other views in the same state.
* You can have views of the same name that live in different states.
* The ui-view can be targeted in a View using the name ([[Ng1StateDeclaration.views]]).
*
* - `autoscroll`: an expression. When it evaluates to true, the `ui-view` will be scrolled into view when it is activated.
* Uses [[$uiViewScroll]] to do the scrolling.
*
* - `onload`: Expression to evaluate whenever the view updates.
*
* #### Example:
* A view can be unnamed or named.
* ```html
* <!-- Unnamed -->
* <div ui-view></div>
*
* <!-- Named -->
* <div ui-view="viewName"></div>
*
* <!-- Named (different style) -->
* <ui-view name="viewName"></ui-view>
* ```
*
* You can only have one unnamed view within any template (or root html). If you are only using a
* single view and it is unnamed then you can populate it like so:
*
* ```html
* <div ui-view></div>
* $stateProvider.state("home", {
* template: "<h1>HELLO!</h1>"
* })
* ```
*
* The above is a convenient shortcut equivalent to specifying your view explicitly with the
* [[Ng1StateDeclaration.views]] config property, by name, in this case an empty name:
*
* ```js
* $stateProvider.state("home", {
* views: {
* "": {
* template: "<h1>HELLO!</h1>"
* }
* }
* })
* ```
*
* But typically you'll only use the views property if you name your view or have more than one view
* in the same template. There's not really a compelling reason to name a view if its the only one,
* but you could if you wanted, like so:
*
* ```html
* <div ui-view="main"></div>
* ```
*
* ```js
* $stateProvider.state("home", {
* views: {
* "main": {
* template: "<h1>HELLO!</h1>"
* }
* }
* })
* ```
*
* Really though, you'll use views to set up multiple views:
*
* ```html
* <div ui-view></div>
* <div ui-view="chart"></div>
* <div ui-view="data"></div>
* ```
*
* ```js
* $stateProvider.state("home", {
* views: {
* "": {
* template: "<h1>HELLO!</h1>"
* },
* "chart": {
* template: "<chart_thing/>"
* },
* "data": {
* template: "<data_thing/>"
* }
* }
* })
* ```
*
* #### Examples for `autoscroll`:
* ```html
* <!-- If autoscroll present with no expression,
* then scroll ui-view into view -->
* <ui-view autoscroll/>
*
* <!-- If autoscroll present with valid expression,
* then scroll ui-view into view if expression evaluates to true -->
* <ui-view autoscroll='true'/>
* <ui-view autoscroll='false'/>
* <ui-view autoscroll='scopeVariable'/>
* ```
*
* Resolve data:
*
* The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
* can be customized using [[Ng1ViewDeclaration.resolveAs]]). This can be then accessed from the template.
*
* Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
* controller is instantiated. The `$onInit()` hook can be used to perform initialization code which
* depends on `$resolve` data.
*
* #### Example:
* ```js
* $stateProvider.state('home', {
* template: '<my-component user="$resolve.user"></my-component>',
* resolve: {
* user: function(UserService) { return UserService.fetchUser(); }
* }
* });
* ```
