Review Comment:
   I will go back and double check that this correct.  However, I did change 
the nomenclature to be speicfic, the list of  `filesToIgnore` should indicate 
that if the pattern is matched the file is excluded (same with directory).  
Previously the name was `fileFilter`  and there it is difficult to know if you 
are including or excluding files in the filter.
