Magically autojump to directories

After installing https://github.com/joelthelion/autojump

brew install autojump

or

port install autojump

you can easily change directories using

j <portion of the directory>

example: you want to change to this directory "~/Documents/long/path/to/projects/pizza"

j pizza

will change the directory to ~/Documents/long/path/to/projects/pizza

• Note: you need to have done atleast one cd on the directory you want to autojump before.
