@description
<b>Added in Umbraco 7.8</b>. The tour component is a global component and is already added to the umbraco markup. 
In the Umbraco UI the tours live in the "Help drawer" which opens when you click the Help-icon in the bottom left corner of Umbraco. 
You can easily add you own tours to the Help-drawer or show and start tours from 
anywhere in the Umbraco backoffice. To see a real world example of a custom tour implementation, install <a href="https://our.umbraco.com/projects/starter-kits/the-starter-kit/">The Starter Kit</a> in Umbraco 7.8

<h1><b>Extending the help drawer with custom tours</b></h1>
The easiet way to add new tours to Umbraco is through the Help-drawer. All it requires is a my-tour.json file. 
Place the file in <i>App_Plugins/{MyPackage}/backoffice/tours/{my-tour}.json</i> and it will automatically be 
picked up by Umbraco and shown in the Help-drawer.

<h3><b>The tour object</b></h3>
The tour object consist of two parts - The overall tour configuration and a list of tour steps. We have split up the tour object for a better overview.
<pre>
// The tour config object
{
    "name": "My Custom Tour", // (required)
    "alias": "myCustomTour", // A unique tour alias (required)
    "group": "My Custom Group" // Used to group tours in the help drawer
    "groupOrder": 200 // Control the order of tour groups
    "allowDisable": // Adds a "Don't" show this tour again"-button to the intro step
    "culture" : // From v7.11+. Specifies the culture of the tour (eg. en-US), if set the tour will only be shown to users with this culture set on their profile. If omitted or left empty the tour will be visible to all users
    "requiredSections":["content", "media", "mySection"] // Sections that the tour will access while running, if the user does not have access to the required tour sections, the tour will not load.   
    "steps": [] // tour steps - see next example
}
</pre>
<pre>
// A tour step object
{
    "title": "Title",
    "content": "<p>Step content</p>",
    "type": "intro" // makes the step an introduction step,
    "element": "[data-element='my-table-row']", // the highlighted element
    "event": "click" // forces the user to click the UI to go to next step
    "eventElement": "[data-element='my-table-row'] [data-element='my-tour-button']" // specify an element to click inside a highlighted element
    "elementPreventClick": false // prevents user interaction in the highlighted element
    "backdropOpacity": 0.4 // the backdrop opacity
    "view": "" // add a custom view
    "customProperties" : {} // add any custom properties needed for the custom view
}
</pre>

<h1><b>Adding tours to other parts of the Umbraco backoffice</b></h1>
It is also possible to add a list of custom tours to other parts of the Umbraco backoffice, 
as an example on a Dashboard in a Custom section. You can then use the {@link umbraco.services.tourService tourService} to start and stop tours but you don't have to register them as part of the tour service.

<h1><b>Using the tour service</b></h1>
<h3>Markup example - show custom tour</h3>
<pre>
    <div ng-controller="My.TourController as vm">

        <div>{{vm.tour.name}}</div>
        <button type="button" ng-click="vm.startTour()">Start tour</button>

        <!-- This button will be clicked in the tour -->
        <button data-element="my-tour-button" type="button">Click me</button>

    </div>
</pre>

<h3>Controller example - show custom tour</h3>
<pre>
    (function () {
        "use strict";

        function TourController(tourService) {

            var vm = this;

            vm.tour = {
                "name": "My Custom Tour",
                "alias": "myCustomTour",
                "steps": [
                    {
                        "title": "Welcome to My Custom Tour",
                        "content": "",
                        "type": "intro"
                    },
                    {
                        "element": "[data-element='my-tour-button']",
                        "title": "Click the button",
                        "content": "Click the button",
                        "event": "click"
                    }
                ]
            };

            vm.startTour = startTour;

            function startTour() {
                tourService.startTour(vm.tour);
            }

        }

        angular.module("umbraco").controller("My.TourController", TourController);

    })();
</pre>

<h1><b>Custom step views</b></h1>
In some cases you will need a custom view for one of your tour steps. 
This could be for validation or for running any other custom logic for that step. 
We have added a couple of helper components to make it easier to get the step scaffolding to look like a regular tour step. 
In the following example you see how to run some custom logic before a step goes to the next step.

<h3>Markup example - custom step view</h3>
<pre>
    <div ng-controller="My.TourStep as vm">

        <umb-tour-step on-close="model.endTour()">
                
            <umb-tour-step-header
                title="model.currentStep.title">
            </umb-tour-step-header>
            
            <umb-tour-step-content
                content="model.currentStep.content">

                <!-- Add any custom content here  -->

            </umb-tour-step-content>

            <umb-tour-step-footer class="flex justify-between items-center">

                <umb-tour-step-counter
                    current-step="model.currentStepIndex + 1"
                    total-steps="model.steps.length">
                </umb-tour-step-counter>

                <div>
                    <umb-button 
                        size="xs" 
                        button-style="success" 
                        type="button" 
                        action="vm.initNextStep()" 
                        label="Next">
                    </umb-button>
                </div>

            </umb-tour-step-footer>

        </umb-tour-step>

    </div>
</pre>

            function initNextStep() {
                // run logic here before going to the next step
                $scope.model.nextStep();
            }

        }

        angular.module("umbraco").controller("My.TourStep", StepController);

 * General-purpose validator for ngModel.
 * angular.js comes with several built-in validation mechanism for input fields (ngRequired, ngPattern etc.) but using
 * an arbitrary validation function requires creation of a custom formatters and / or parsers.
 * The ui-validate directive makes it easy to use any function(s) defined in scope as a validator function(s).
 * A validator function will trigger validation on both model and input changes.
 *
 * @example <input val-custom=" 'myValidatorFunction($value)' ">
 * @example <input val-custom="{ foo : '$value > anotherModel', bar : 'validateFoo($value)' }">
 * @example <input val-custom="{ foo : '$value > anotherModel' }" val-custom-watch=" 'anotherModel' ">
 * @example <input val-custom="{ foo : '$value > anotherModel', bar : 'validateFoo($value)' }" val-custom-watch=" { foo : 'anotherModel' } ">
 *
 * @param val-custom {string|object literal} If strings is passed it should be a scope's function to be used as a validator.
 * If an object literal is passed a key denotes a validation error key while a value should be a validator function.
 * In both cases validator function should take a value to validate as its argument and should return true/false indicating a validation result.

* @ngdoc directive
* @name umbraco.directives.directive:valPropertyValidator
* @restrict A
* @description Performs any custom property value validation checks on the client side. This allows property editors to be highly flexible when it comes to validation
                on the client side. Typically if a property editor stores a primitive value (i.e. string) then the client side validation can easily be taken care of 
                with standard angular directives such as ng-required. However since some property editors store complex data such as JSON, a given property editor
                might require custom validation. This directive can be used to validate an Umbraco property in any way that a developer would like by specifying a
                callback method to perform the validation. The result of this method must return an object in the format of 
                {isValid: true, errorKey: 'required', errorMsg: 'Something went wrong' }
                The error message returned will also be displayed for the property level validation message.
                This directive should only be used when dealing with complex models, if custom validation needs to be performed with primitive values, use the simpler 
                angular validation directives instead since this will watch the entire model.
