Make help menu, also refactor code

[mxms0]

Code needs a bit of cleaning and refactor. Have to remove system() calls for making directories, remove some test functions, and general more practical code.

@Maximus- Thanks for making this utility. I am dumping from the app. but all I see are system classes.
I would like to see the result like class-dump-z. Am I not using it right?
