setup_fabsim needs to be clarified

[djgroen]

"Fabsim wouldn't install because of an issue with ssh-ing from the local host back to itself. I had to install it on a lab computer instead."

I now clarified the setup_fabsim command. It outputs as follows:

derek@vecma01:~/Codes/FabSim3/base$ fab localhost setup_fabsim
MODULE COMMANDS:  []
{'all': [], 'dummy': []}
MODULE COMMANDS:  []
[derek@localhost] Executing task 'setup_fabsim'
To set up your SSH keys, you will be logged in to your local machine once using SSH. You may be asked to provide your password once to facilitate this login.
local id_rsa key already exists.
[localhost] local: ssh-copy-id -i ~/.ssh/id_rsa.pub derek@localhost 2>ssh_copy_id.log
derek@localhost's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'derek@localhost'"
and check to make sure that only the key(s) you wanted were added.

[derek@localhost] run: mkdir -p /home/derek/FabSim3/config_files; mkdir -p /home/derek/FabSim3/results; mkdir -p /home/derek/FabSim3/scripts
[localhost] local: mkdir -p /home/derek/Codes/FabSim3/plugins
[localhost] local: rm -rf /home/derek/Codes/FabSim3/plugins/FabDummy
[localhost] local: git clone https://github.com/djgroen/FabDummy.git /home/derek/Codes/FabSim3/plugins/FabDummy

Done.
Disconnecting from localhost... done.

...and while I was at it, I disabled the weird "MODULE COMMANDS" output as well.
