Generalize code to not be so opinionated #12
Description
Right now, the nodegraph is very opinionated for Gimel Studio's purpose. We should move the non-general code to Gimel Studio itself and change the api to allow gsnodegraph to be used for other projects.
A few rough ideas:
- Make "hooks" to allow custom stuff to be drawn on nodes, etc
- Make the widget to not be so opinionated in how it reads properties, how the registry is setup, etc
