This took much longer than expected, but the KiCad evaluator is finally here, fully functional and ready to roll. What a Rust adventure and learning experience this has been :sweat_smile: This initial implementation of the evaluator supports the following features (out of all currently planned features):
[x] Evaluation of all default and custom-defined expressions defined in component attributes.
[x] Full namespace support, attributes of components defined in child schematics in the KiCad hierarchical schematic model can be accessed via <schematic>.<component>.<attribute>, e.g. DCDC.R3.Tolerance. (Parent schematics cannot be accessed by design to preserve the capability of evaluating every schematic independently.)
[x] Order-independent evaluation using a recursive dependency resolver.
[x] Self-dependency and circular dependency detection.
[x] Automatic appending of the unit for an attribute if provided.
[x] Automatic parsing of numeric types for the value field (if no string-based unit is given).
[x] Support for global overrides (using text field parsing or a custom KiCad component).
[x] Support for support functions such as voltage_divider(...) (either baked-in or loaded externally).
[x] Applying the updates from the internal Schematic format back into the kicad_parse_gen::schematic::Schematic (#18).
As evidenced by the rather large commits, this has gone through many revisions until I finally figured out how to implement this properly in Rust. Thus, I suggest squashing the commits when merging. I'm also aware that the code is a bit lightly commented right now due to lack of time, but I will improve that front with upcoming PRs. I can however also add the comments to this PR if that's preferred.
