Appvayor failures seems to be caused by too old compiler. |
So the only policy is that it should build for windows 😁 |

Resolves #86.
Adds a method
NodeId::debug_pretty_print(arena :&mut Arena<T>) -> DebugPrettyPrint<'_, T>that enables a (sub)tree to be pretty-printed.See
tests/debug_pretty_print.rsfor (current) expected outputs.A note about licensing
Most of the codes are derived from my crates treena and dendron (yeah, this man is writing tree manipulation crates again and again for some reason! 🤣).
Those pretty-printing implementations are also written by me and distributed by MIT/Apache-2.0, and this pull request is written and submitted by me (the same person), so I believe there are no licensing issues.
(Just in case: I hereby declare that I permit
indextree(and other derived works) to treat these codes under MIT license.)
