  === Pebble template engine
  
  To use Pebble, you need to add the following _dependency_ to your project:
  `io.vertx:vertx-web-templ-pebble:3.4.0-SNAPSHOT`. Create an instance of the Pebble template engine
  using: `io.vertx.ext.web.templ.PebbleTemplateEngine#create(vertx)`.
  
  When using the Pebble template engine, it will by default look for
  templates with the `.peb` extension if no extension is specified in the file name.
  
  The routing context `link:../../apidocs/io/vertx/ext/web/RoutingContext.html[RoutingContext]` is available
  in the Pebble template as the `context` variable, this means you can render the template based on anything in the context
  including the request, response, session or context data.
  
  Here are some examples:
  
  ----
  [snip]
  <p th:text="{{context.foo}}"></p>
  <p th:text="{{context.bar}}"></p>
  <p th:text="{{context.normalisedPath()}}"></p>
  <p th:text="{{context.request().params().param1}}"></p>
  <p th:text="{{context.request().params().param2}}"></p>
  [snip]
