No install tip for tree command

[soutys]

Sometimes tree command is not installed by default.

RHEL / CentOS / Fedora Linux:
# yum install tree
Debian / Mint / Ubuntu Linux:
$ sudo apt-get install tree

Thank you, we will update the scenario.

I would suggest not overloading the scenario with non-native tools (it's always a pain to install something, and we don't want to have the students spend too much time on things that are not necessary), and simply remove the use of tree and replace it with some combination of ls or dir.

tree is a MSW built-in tool. With almost all linux distros you can use something like this:
ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'
(from http://www.centerkey.com/tree/)
It works but it's a little bit hairy :)

@AdrianGaudebert maybe you can create pull request with the change? I think it is a good idea but I'm afraid this ticket might be forgotten for another few months...
