* Twig base exception.
*
* This exception class and its children must only be used when
* an error occurs during the loading of a template, when a syntax error
* is detected in a template, or when rendering a template. Other
* errors must use regular PHP exception classes (like when the template
* cache directory is not writable for instance).
*
* To help debugging template issues, this class tracks the original
template
* name and line where the error occurred.
*
* Whenever possible, you must set these information (original template
name
* and line number) yourself by passing them to the constructor. If some or
all
* these information are not available from where you throw the exception,
then
* this class will guess them automatically (when the line number is set to
-1
* and/or the name is set to null). As this is a costly operation, this
* can be disabled by passing false for both the name and the line number
* when creating a new instance of this class.
