while technically public, the line_segment_distance is in a hidden private_utils module exported by the geo-types crate. this change is fine with me, but i'm wondering if including it in CHANGES.md could cause confusion since the function is not in the rustdoc output

Yeah, I waffled on this. Since you also brought it up, I'm going to remove it. |

639: Introduce the geomgraph module for DE-9IM Relate trait r=michaelkirk a=michaelkirk - [x] I agree to follow the project's [code of conduct](https://github.com/georust/geo/blob/master/CODE_OF_CONDUCT.md). - [x] I added an entry to `CHANGES.md` if knowledge of this change could be valuable to users. --- Fixes #513, #515 (I'm sorry it's so large) ~~I'm going to leave it as a draft (edit: 🤦 I failed to actually open the PR as a draft) while I wait to merge #636 and #638 and then do some rebasing, but I don't anticipate doing other large changes before review.~~ *update: ready for review!* Here's some of the earlier work in pursuit of this: #514 #516 #523 #524 #538 #552 #561 #611 #628 #629 #636 Primarily, this introduces the geomgraph module for a DE-9IM `Relate` trait. geomgraph implements a topology graph largely inspired by JTS's module of the same name: https://github.com/locationtech/jts/tree/jts-1.18.1/modules/core/src/main/java/org/locationtech/jts/geomgraph You can see some of the reference code if you omit the "REMOVE JTS COMMENTS" commit. In some places the implementation is quite close to the JTS source. The overall "flow" is pretty similar to that of JTS, but in the small, there were some divergences. It's not easy (or desirable) to literally translate a Java codebase making heavy use of inheritance and pointers to rust. Additionally, I chose to take advantage of `Option` and rust's enums with associated data to make some case analysis more explicit. There is a corresponding PR in our [jts-test-runner](georust/jts-test-runner#6) crate which includes the bulk of the tests for the new Relate trait. ## Algorithm Overview This functionality is accessed on geometries, via the `Relate` trait, e.g. `line.relate(point)` which returns a DE-9IM [`IntersectionMatrix`](https://en.wikipedia.org/wiki/DE-9IM#Matrix_model). The `Relate` trait is driven by the `RelateOperation`. The `RelateOperation` builds a `GeometryGraph` for each of the two geometries being related. A `GeometryGraph` is a systematic way to organize the "interesting" parts of a geometry's structure - e.g. where its vertices, lines, and areas lie relative to one another. Once the `RelateOperation` has built the two `GeometryGraph`s, it uses them to efficiently compare the two Geometries's structures, outputting the `IntesectionMatrix`.
