- Temp cde
- make it build
- More fix
- Now it works without wild pointer.
- Only clone if objects come from input
- Made incremental builds work, fixed nasty bug
- Added metadata outputting
	- Built hash
	- Pointers existing in object
- More meta data for packaging
- Fixed reloading of metadata for incremental buildswq
- bit prepareing
- Builder fixes
- Add parent db option for path lookups.

  Idea is if pathof() is called on objects referenced by other objects
  in a db, but referenced objects point to a previous (parent) db, then
  they cannot know the path.
- Fixed parent fixing for multi level
