class TwigSimpleCheckToStringNode

Defines a twig node for simplifying CheckToStringNode.

Drupal's sandbox policy is very permissive with checking whether an object can be converted to a string. We allow any object with a __toString method. This means that the array traversal in the default SandboxExtension implementation added by the parent class is a performance overhead we don't need.
