Implementation function:
1. Find citations
View all resources referenced by a file
2. Find cited parties
View the reference relationship of a resource
3. Reference relationship list
View the citation relationships of all resources. You can search by name and view citation details.
4. Referenced relationship list
View the reference relationships of all resources, categorized by file extensions, search by name, and view reference details
5. Direct/recursive reference
You can choose to view only direct references (direct dependencies) or recursive references (indirect dependencies)
