Displaying graphs or help currently does not work.

For the display graph part we currently get:

`i10 : displayGraph A
-- running: dot -Tjpg /tmp/M2-17-0/2.dot -o /tmp/M2-17-0/3.jpg
-- running: display /tmp/M2-17-0/3.jpg &
sh: 1: display: not found`

This can probably be fixed with a symlink replacing display.

The help does not work due to a version number issue. It has already been fixed but needs to be deployed.
