Make a copy of Files.html in your repo

Modify the JS code so that it finds 
a local copy of a given remote file:

* Enter URL of the remote file in your repo as the input
(Text files are modified in Windows -- better to use binary)
* Select some local files (all in the same folder)
* Search for the same length and type among selected files
* Report "different" OR "found" based on length and type, 
  not name or content

Take a partial screen shot of your page
