Scala Worksheet to test the usage of JGit

   - I used the Typesafe Scala IDE (Eclipse and a bit more)
   - Downloaded JGit (2.1.0.201209190230-r) from http://eclipse.org/jgit/download/
   - Donloaded JSch (Java Secure Channel, jsch-0.1.49.jar) from http://www.jcraft.com/jsch/
   - Put both in the build path.
   - Created a worksheet. (This one.)
   - Play around.
