Added program specific configurations in config.yaml under puudot
and added key for verbose mode. Currently verbose mode prints
'dot' information when running the program.
Refactored puudot.py and graph.py in order to allow easier
addition of output formats.
Created execution script for the container image and moved code
copy from Dockerfile to volume in compose.
Now code changes don't require image rebuild.
Implemented code for the first test version.
Added Docker funtionality.
Define data location in compose and run:
docker compose up
Removed test data from the repository.
