Automatic class diagram construction

[emmuhamm]

Description

Fixes #57

WIP

python style_pyreverse.py daqpytools --output-directory pics
python split_diagram.py pics/classes_styled.dot --output-directory pics/split

Make the above a callable script! And everyone will be happy

Make it possible to define your own stylistic yaml file or whatever and pass that in the python script

Maybe this should be a new folder in daqpytools called either docs or UML or whatever
