Uses the currently selected node and transformation to assemble the destination path for the file.

The Twig writer accepts the use of a Query to be able to generate output for multiple objects using the same
template.

The given node is the result of such a query, or if no query given the selected element, and the transformation
contains the destination file.

Since it is important to be able to generate a unique name per element can the user provide a template variable
in the name of the file.
Such a template variable always resides between double braces and tries to take the node value of a given
query string.

Example:

An artifact stating `classes/{{name}}.html` will try to find the
node 'name' as a child of the given $node and use that value instead.

@param DescriptorAbstract $node
@param Transformation     $transformation

@throws \InvalidArgumentException if no artifact is provided and no routing rule matches.
@throws \UnexpectedValueException if the provided node does not contain anything.

@return string|false returns the destination location or false if generation should be aborted.
