/**
 * This directive allows for access to the whole `data` property defined in the current [Route](https://angular.io/api/router/Route#data) from a Component's template.
 *
 * @example
 * <!-- We can use it as following: -->
 * <h1 *tdRouteData="let data">
 *   Current title is: {{ data.title }}
 * </h1>
 *
 * @example
 * <!-- It is also possible to pass a default value so that if a property is not defined in the Route we will still receive some value: -->
 * <h1 *tdRouteData="let data; defaultValue: { title: 'DefaultTitle', routeTags: ['defaultTag'] }">
 *   Current title is: {{ data.title }}
 * </h1>
 *
 * @example
 * <!-- If you want to access multiple properties in one component's template it is **recommended** to wrap the whole template with only one `*tdRouteData` directive. This approach follows DRY principle and is efficient as it only creates one subscription per template. -->
 * <ng-container *tdRouteData="let data; defaultValue: { title: 'DefaultTitle', routeTags: ['defaultTag'] }">
 *   <h1>
 *     Current title is: {{ data.title }}
 *   </h1>
 *   <p>
 *     Current route contains the following tags: {{ data.routeTags | json }}
 *   </p>
