IsPathPossible with ITraversable

As the title suggests, path utility for IsPathPossible, though more than just an additional tag.

If you want I can add try adding this feature and provide a git.patch

As promised here is the patch file for it: https://gist.github.com/WolfVanH/6c772dfb2067e957fa570e322308045c
This was made using version 4.2.8

I’ve tested the implementation ( Only IsPathPossible ), and can provide a test scene if desired.
