 - Refactored the code: It is now easier to add new paths.
 (1) A list of possible file name candidates is created.
 (2) This list is sequentially checked for file existence. A
     possibly missing file extension is considered in this step.
     Thus, we have no code repetition.
 (3) A file which is identified as present, is opened.
