owl-bt/src/client/app/tree/missingNodeItemDescValidation/missingNodeItemDescValidation.service.js

owl-bt is editor for Behavior trees. It has been inspired by Unreal engine behavior trees in a way, that it supports special node items like decorators and services. This makes trees smaller and much more readable.
