So i have added a new sub-system that combines the git loading and the JSON parser to load, modify and publish sets of measurements that correspond to specific parts in the real world. I have servos, steppers, bearing belts nuts and it all was compiled by Steve Kelly for a totally different programmatic cad package. Because it was isolated well, i was able to load in directly and start using the parts.

here is an example of the syntax https://gist.github.com/madhephaestus/033482ccab38baa08d9e84bf224e7823

this should be availible in the 0.15.7 release.
