Challenge: .tar and .tgz Files

A listing of files in a zip file is given by zipinfo. You can get a similar listing for tar files by using the command-line tool tar:

#​ ​/​u​s​r​/​b​i​n​/​t​a​r​ ​t​f​ ​M​y​F​i​l​e​s​.​t​a​r​

If the tar file is also compressed, just add a z to the flags:

#​ ​/​u​s​r​/​b​i​n​/​t​a​r​ ​t​z​f​ ​M​y​F​i​l​e​s​.​t​g​z​

Extend ZIPspector to deal with .tar and .tgz files.
