This function works on an assumed order of precendence:
- we start by assuming all projects as complete (eg only DONE and CANCELLED)
- if project has any TODO (regardless of DONE or CANCELLED) it is stuck
- if project has any HOLD (regardless of DONE, CANCELLED, or TODO) it is held
- in the same manner WAITING means waiting project
2018-04-08 21:54:20 -04:00
- in the same manner, NEXT or scheduled means active.
- can also detect errors which override all
- anything higher than active breaks the recursion/tree walk
2018-04-02 00:40:42 -04:00
