Detailed Description

Twig_Node_SandboxedPrint adds a check for the __toString() method when the variable is an object and the sandbox is activated.

When there is a simple Print statement, like {{ article }}, and if the sandbox is enabled, we need to check that the __toString() method is allowed if 'article' is an object.
