I've just posted my first gem and I'm really proud of it. I have a feeling there are people out there who could get some value out of it as well. I'm also interested in having the code and concept critiqued. I'm using this in production right now to design a application for a university neuroscience lab where there are a huge number of classes that all have completely different attributes but fit into groups which have consistent relationships to each other. This has allowed me to have a very cleanly implemented data model which would have been an absolute mess without this tool. All feedback appreciated.
