I have replaced all instances of `HashMap<...>` with `BTreeMap<...>`,
of `HashSet<...>` with `BTreeSet<...>`, and all the uses of the `Hash`
trait with `Ord`.
I have done a few manual tests and found the behavior to be
deterministic between the GUI application launches. However, undoing an
autoroute command and then manually executing it once again continues to
produce variable results. I suppose this is because of some bug in the
code where edits are applied. Hence, the issue
https://codeberg.org/topola/topola/issues/46
is only partially resolved.
I ran the following command in Fish shell:
```
reuse annotate --skip-unrecognised --copyright="Topola contributors" --license="MIT" **.{rs,md,toml}
```
The choice of year 2024 in the copyright statements is intentional.
Disambiguate between node indices and (teir inner) petgraph indices.
Rename "band index" to "band first seg index", as we identify bands by
teir first segs. Rename "trianvertex index" and "navvertex index"
respectively to "trianvertex node index" and "navvertex node index", as
these point to nodes on the geometry graph and only indirectly to
vertices on the vertex graph.
