/**
 * Enables the router link DSL.
 *
 * Warning. This feature is experimental and can change.
 *
 * To enable the transformer pass the router link DSL provider to `bootstrap`.
 *
 * ## Example:
 * ```
 * import {bootstrap} from 'angular2/platform/browser';
 * import {ROUTER_LINK_DSL_PROVIDER} from 'angular2/router/router_link_dsl';
 *
 * bootstrap(CustomApp, [ROUTER_LINK_DSL_PROVIDER]);
 * ```
 *
 * The DSL allows you to express router links as follows:
 * ```
 * <a [routerLink]="route:User"> <!-- Same as <a [routerLink]="['User']"> -->
 * <a [routerLink]="route:/User"> <!-- Same as <a [routerLink]="['User']"> -->
 * <a [routerLink]="route:./User"> <!-- Same as <a [routerLink]="['./User']"> -->
 * <a [routerLink]="./User(id: value, name: 'Bob')"> <!-- Same as <a [routerLink]="['./User', {id:
 * value, name: 'Bob'}]"> -->
 * <a [routerLink]="/User/Modal"> <!-- Same as <a [routerLink]="['/User', 'Modal']"> -->
 * <a [routerLink]="User[Modal]"> <!-- Same as <a [routerLink]="['User', ['Modal']]"> -->
 * ```
