/**
 * @module mobile-angular-ui.core.activeLinks
 * @description
 *
 * `mobile-angular-ui.activeLinks` module sets up `.active` class for `a`
 * elements those `href` attribute matches the current angular `$location` url.
 * It takes care of excluding both search part and hash part from comparison.
 *
 * `.active` classes are added/removed each time one of `$locationChangeSuccess`
 * or `$includeContentLoaded` is fired.
 *
 * ## Usage
 *
 * Just declare it as a dependency to your app unless you have already included
 * one of its super-modules.
 *
 * ```
 * angular.module('myApp', ['mobile-angular-ui.core.activeLinks']);
 * ```
 *
 * **NOTE:** if you are using it without Bootstrap you may need to add some css
 * to your stylesheets to reflect the activation state of links. I.e.
 *
 * ``` css
 * a.active {
 *   color: blue;
 * }
 * ```

/**
 * @module mobile-angular-ui.core.capture
 * @description
 *
 * The `capture` module exposes directives to var you extract markup which can
 * be used in other parts of a template using `uiContentFor` and `uiYieldTo`
 * directives.
 *
 * It provides a way to move or clone a block of markup to other parts of the document.
 *
 * This method is particularly useful to setup parts of the layout within an
 * angular view. Since blocks of html are transplanted within their original
 * `$scope` is easy to create layout interactions depending on the context.
 * Some tipical task you can accomplish with these directives are: _setup
 * the navbar title depending on the view_ or _place a submit button for a
 * form inside a navbar_.
 *
 * ## Usage
 *
 * Declare it as a dependency to your app unless you have already included some
 * of its super-modules.
 *
 * ```
 * angular.module('myApp', ['mobile-angular-ui']);
 * ```
 *
 * Or
 *
 * ```
 * angular.module('myApp', ['mobile-angular-ui']);
 * ```
 *
 * Or
 *
 * ```
 * angular.module('myApp', ['mobile-angular-ui.core.capture']);
 * ```
 *
 * Use `ui-yield-to` as a placeholder.
 *
 * ``` html
 * <!-- index.html -->
 *
 * <div class="navbar">
 *   <div ui-yield-to="title" class="navbar-brand">
 *     <span>Default Title</span>
 *   </div>
 * </div>
 *
 * <div class="app-body">
 *   <ng-view class="app-content"></ng-view>
 * </div>
 * ```
 *
 * Use `ui-content-for` inside any view to populate the `ui-yield-to` content.
 *
 * ``` html
 * <!-- myView.html -->
 *
 * <div ui-content-for="title">
 *   <span>My View Title</span>
 * </div>
 * ```
 *
 * Since the original scope is preserved you can use directives inside
 * `ui-content-for` blocks to interact with the current scope. In the following
 * example we will add a navbar button to submit a form inside a nested view.
 *
 * ``` html
 * <!-- index.html -->
 *
 * <div class="navbar">
 *   <div ui-yield-to="navbarAction">
 *   </div>
 * </div>
 *
 * <div class="app-body">
 *   <ng-view class="app-content"></ng-view>
 * </div>
 * ```
 *
 * ``` html
 * <!-- newCustomer.html -->
 *
 * <form ng-controller="newCustomerController">
 *
 *   <div class="inputs">
 *     <input type="text" ng-model="customer.name" />
 *   </div>
 *
 *   <div ui-content-for="navbarAction">
 *     <button ng-click="createCustomer()">
 *       Save
 *     </button>
 *   </div>
 *
 * </form>
 * ```
 *
 * ``` javascript
 * app.controller('newCustomerController', function($scope, Store){
 *   $scope.customer = {};
 *   $scope.createCustomer = function(){
 *     Store.create($scope.customer);
 *     // ...
 *   }
 * });
 * ```
 *
 * If you wish you can also duplicate markup instead of move it. Just add `duplicate` parameter to `uiContentFor` directive to specify this behaviour.
 *
 * ``` html
 * <div ui-content-for="navbarAction" duplicate>
 *   <button ng-click="createCustomer()">
 *     Save
 *   </button>
 * </div>
 * ```

  /**
   * @module mobile-angular-ui.core.sharedState
   *
   * @description
   * `mobile-angular-ui.core.sharedState` is expose the homonymous service
   * `SharedState` and a group of directives to access it.
   *
   * `SharedState` allows to use elementary angular or angularish directives
   * to create interactive components.
   *
   * Ie.
   *
   * ``` html
   * <div class="nav nav-tabs" ui-shared-state='activeTab'>
   *   <a ui-set="{activeTab: 1}">Tab1</a>
   *   <a ui-set="{activeTab: 2}">Tab2</a>
   *   <a ui-set="{activeTab: 3}">Tab3</a>
   * </div>
   * <div class="tabs">
   *   <div ui-if="activeTab == 1">Tab1</div>
   *   <div ui-if="activeTab == 2">Tab2</div>
   *   <div ui-if="activeTab == 3">Tab3</div>
   * </div>
   * ```
   *
   * Using `SharedState` you will be able to:
   *
   * - Create interactive components without having to write javascript code
   * - Have your controller free from UI logic
   * - Separe `ng-click` triggering application logic from those having a visual effect only
   * - Export state of components to urls
   * - Easily make components comunicate each other
   *
   * Also note that:
   *
   * Data structures retaining statuses will stay outside angular scopes
   * thus they are not evaluated against digest cycle until its necessary.
   * Also although statuses are sort of global variables `SharedState` will
   * take care of disposing them when no scopes are requiring them anymore.
   *
   * A set of `ui-*` directives are available to interact with `SharedState`
   * module and will hopefully var you spare your controllers and your time
   * for something that is more meaningful than this:
   *
   * ``` js
   * $scope.activeTab = 1;
   *
   * $scope.setActiveTab = function(n) {
   *   $scope.activeTab = n;
   * };
   * ```
   *
   * ## Usage
   *
   * Declare it as a dependency to your app unless you have already included some
   * of its super-modules.
   *
   * ```
   * angular.module('myApp', ['mobile-angular-ui.core.sharedState']);
   * ```
   *
   * Use `ui-shared-state` directive to require/initialize a state from the target element scope
   *
   * **Example.** Tabs
   *
   * <iframe class='embedded-example' src='/examples/tabs.html'></iframe>
   *
   * **Example.** Custom components
   *
   * <iframe class='embedded-example'  src='/examples/lightbulb.html'></iframe>
   *
   * NOTE: `ui-toggle/set/turnOn/turnOff` responds to `click/tap` without
   * stopping propagation so you can use them along with ng-click too.
   * You can also change events to respond to with `ui-triggers` attribute.
   *
   * Any `SharedState` method is exposed through `Ui` object in `$rootScope`.
   * So you could always do `ng-click="Ui.turnOn('myVar')"`.
   *
   * Since `SharedState` is a service you can initialize/set statuses through
   * controllers too:
   *
   * ``` js
   * app.controller('myController', function($scope, SharedState){
   *   SharedState.initialize($scope, "activeTab", 3);
   * });
   * ```
   *
   * As well as you can use `ui-default` for that:
   *
   * ``` html
   * <div class="tabs" ui-shared-state="activeTab" ui-default="thisIsAnExpression(5 + 1 - 2)"></div>
   * ```
   *

   *
   * It acts as a BUS between UI elements to share UI related state that is

   * although statuses are sort of global variables `SharedState` will take
   * care of disposing them when no scopes are requiring them anymore.
   *
   * A set of `ui-*` directives are available to interact with `SharedState`
   * module and will hopefully var you spare your controllers and your time for
   * something that is more meaningful than this:

   * ``` js

   *
   * $scope.setActiveTab = function(n) {
   *   $scope.activeTab = n;

  /**
   * @name uiScopeContext
   * @inner
   * @description
   *
   * `uiScopeContext` is not a directive, but a parameter common to any of the
   * `ui-*` directives in this module.
   *
   * By default all `ui-*` conditions in this module evaluates in the context of
   * `SharedState` only, thus scope variable are not accessible. To use them you have
   * two options:
   *
   * #### 1. pre-interpolation
   *
   * You can use pre-interpolation in expression attribute. For instance the following syntax
   * is ligit:
   *
   * ``` html
   * <div ui-if='state{{idx}}'><!-- ... --></div>
   * ```
   *
   * In this case `idx` value is taken from scope and embedded into
   * conditions before parse them.
   *
   * This works as expected and is fine for the most cases, but it has a little caveat:
   *
   * The condition has to be re-parsed at each digest loop and has to walk scopes
   * in watchers.
   *
   * #### 2. uiScopeContext
   *
   * If you are concerned about performance issues using the first approach
   * `uiScopeContext` is a more verbose but also lightweight alternative
   * to accomplish the same.
   *
   * It allows to use current scope vars inside `ui-*` conditions, leaving
   * other scope vars (or the entire scope if not present) apart from the
   * condition evaluation process.
   *
   * Hopefully this will keep evaluation running against a flat and small data
   * structure instead of taking into account the whole scope.
   *
   * It is a list `scopeVar[ as aliasName] [, ...]` specifing one of more scope
   * variables to take into account when evaluating conditions. ie:
   *
   * ``` html
   * <!-- use item from ng-repeat -->
   * <div ui-if="openPanel == i" ui-scope-context='i' ng-repeat="i in [1,2,3]">
   *   <div class="panel-body">
   *     <!-- ... -->
   *   </div>
   * </div>
   * ```
   *
   * ``` html
   * <div ui-if="sharedState1 == myVar1 && sharedState2 == myVar2"
   *   ui-scope-context="myVar1, myVar2"
   * >
   * </div>
   * ```
   *
   * Be aware that scope vars will take precedence over sharedStates so,
   * in order to avoid name clashes you can use 'as' to refer to scope vars
   * with a different name in conditions:
   *
   * ``` html
   * <div ui-if="x == myVar1 && y == myVar2"
   *   ui-scope-context="x as myVar1, y as myVar2"
   * >
   * </div>
   * ```

/**
 * Provides directives and service to prevent touchmove default behaviour
 * for touch devices (ie. bounce on overscroll in IOS).
 *
 * #### Usage
 *
 * Use `ui-prevent-touchmove-defaults` directive on root element of your app:
 *
 * ``` html
 * <body ng-app='myApp' ui-prevent-touchmove-defaults>
 *   <!-- ... -->
 * </body>
 * ```
 *
 * Doing so `touchmove.preventDefault` logic for inner elements is inverted,
 * so any `touchmove` default behaviour is automatically prevented.
 *
 * If you wish to allow the default behaviour, for example to allow
 * inner elements to scroll, you have to explicitly mark an event to allow
 * touchmove default.
 *
 * Mobile Angular UI already handles this for `scrollable` elements, so you don't have
 * to do anything in order to support scroll.
 *
 * If you wish to allow touchmove defaults for certain element under certain conditions
 * you can use the `allowTouchmoveDefault` service.
 *
 * ie.
 *
 * ``` js
 * // always allow touchmove default for an element
 * allowTouchmoveDefault(myelem);
 * ```
 *
 * ``` js
 * // allow touchmove default for an element only under certain conditions
 * allowTouchmoveDefault(myelem, function(touchmove){
 *   return touchmove.pageY > 100;
 * });
 * ```
 *
