Uncaught exception on unexisting folder

$ gitinspector unexisting-folder
Traceback (most recent call last):

    os.chdir(path)
OSError: [Errno 2] No such file or directory: '/home/foxy/unexisting-folder'

This could be handles via an error message, so a simple exception catch would do the trick. I am willing to open a PR if necessary.
