Move all Doodle source code into the src/ subpackage and move the publicly shareable stuff into lib/, for example lib/ui and lib/render. This cleans up the git root and helps make the Doodle UI library more easily publishable as a separate open source project. Currently both lib/ui and lib/render import one or two things from doodle/src that need to be broken apart.
