GetAllExternalReferences4 returns dependencies we don't want #33

GetAllExternalReferences4 returns dependencies based on external references from sketch entity constraints. This type of external reference is created, for example, when editing a part in the context of a parent assembly, and creating a constraint to locate a hole relative to something in the assembly. It is indicated in the feature tree for the part by an arrow ("->") next to the feature with the external reference.

The result is that much more stuff gets committed than the user expects. That's because the assembly is a dependency of the part, so the assembly and all of its components get committed when the user intended to only commit the part.

We may be able to limit returned dependencies with a search filter. Take a look at the SwDmSearchFilters Enumeration. It appears that the SwDmSearchInContextReference filter groups in-context assembly references with a lot of other types of references. I'm not sure we can use this filter.

SwDmSearchInContextReference: 32 = Search for base parts for derived parts, mirrored parts, derived component parts, and in-context assembly references

No, don't use SwDmSearchInContextReference(32). We want dependencies on derived and mirrored parts. We just don't want the part in-context references.

Another possibly solution: when we loop through the referenced documents, discard references where the parent is a part and the child is an assembly.
