Add categories and flipping table

[innyso]

I have been using the following code locally not sure whether this is going to be useful for other people or not but thought I will share it.

1. include the commander module to make parsing of command flag easier
2. include categories for the list of face so that we can choose what to output (so that I can use it for my git commit hook (ʘ‿ʘ) )

I didnt end up categorizing everything tho.
