Vectornaut 65cee1ecc2 Clean up the outline view (#19) 
Clean up the source code and interface of the outline view. In addition, [fix a bug](commit/6e42681b719d7ec97c4225ca321225979bf87b56) that could cause `Assembly::realize` to react to itself under certain circumstances. Those circumstances arose, making the bug noticeable, while this branch was being written.

#### Source code

- Modularize the `Outline` component into smaller components.
- Switch from static iteration to dynamic Sycamore lists. This reduces the amount of re-rendering that happens when an element or constraint changes. It also allows constraint details to stay open or closed during constraint updates, rather than resetting to closed.
- Make `Element::index` private, as discussed [here](pulls/15#issuecomment-1816).

#### Interface

- Make constraints editable, updating the assembly realization on input. Flag constraints where the Lorentz product value doesn't parse.
- Round element vector coordinates to prevent the displayed strings from overlapping.

Note that issue #20 was created by this PR, but it will be addressed shortly.

Abstract

Constraint-based three-dimensional dynamic geometry

Description

From a thorough web search, there does not seem to be a dynamic geometry software package which (a) began its life handling three dimensions, rather than just two, and (b) allows you to express the desired geometric configuration in terms of constraints on the entities (e.g. l and k are parallel, a, b, and c a collinear, etc.) rather than as a construction (e.g. l is the perpendicular bisector of a and b). The goal of the dyna3 project is to close this gap.

Note that currently this is just the barest beginnings of the project, more of a framework for developing dyna3 rather than anything useful.

Implementation goals

  • Comfortable, intuitive UI

  • Able to run in browser (so implemented in WASM-compatible language)

  • Produce scalable graphics of 3D diagrams, and maybe STL files (or other fabricatable file format) as well.
