Thanks Hartmut for getting back to me on this. I'm sorry to have missed this originally /caught in my spam filter)

However, I need to add the caveat that I will certainly need some guidance and direction from those with considerable more experience than myself. For example, to understand the previous attempts and what was deemed lacking or problematic with the designs, what would be the broader design goals for this module, etc. If someone is interested and available to assist and provide guidance, advice, etc. - basically to act as a mentor for this project - I would be very happy for the help and would be willing to contribute to this project to the best of my abilities.
