So this is where I ripped out the guts of the dependency tree and made it a little better defined in some ways, and delayed populating it in others. The validate function signature has changed and I'm still up in the air whether to validate with True/False or throw/catch exceptions. So now, configurables have a list of requirements, these are then bundled into a single requirement and can be passed to automagic. Automagic runs a set of things over the deptree to help build/manage it. These run in order of priority. The tree is still built from the top down, but now automagic can build branch from the bottom up and try and splice them into the tree where appropriate. Hopefully this will make it easier to see follow.
