/**
* Render a string template after applying context filters
* Use examples in the Html::link() method:
* `return $this->_render(__METHOD__, 'link', compact('title', 'url', 'options'), $scope);`
*
* @param string $method name of method that is calling the render (for context filters)
* @param string $string template key (in Helper::_strings) to render
* @param array $params associated array of template inserts {:key} will be replaced by value
* @param array $options Available options:
* - `'handlers'` _array_: Before inserting `$params` inside the string template,
* `$this->_context`'s handlers are applied to each value of `$params` according
* to the key (e.g `$params['url']`, which is processed by the `'url'` handler
* via `$this->_context->applyHandler()`).
* The `'handlers'` option allow to set custom mapping beetween `$params`'s key and
* `$this->_context`'s handlers. e.g. the following handler:
* `'handlers' => array('url' => 'path')` will make `$params['url']` to be
* processed by the `'path'` handler instead of the `'url'` one.
* @return string Rendered HTML
