Added default target file and path parameters

* the transformation is now provided with default parameters such as the target file and its parent directory
* added appropriate test case
** default_params
* test frontend now doesn't provide a "test" parameter anymore
* extracted parameter setter into separate member method "setParameters" of TransformationFacade
