Describe the solution you'd like
I would like an option added to hyde, --infer-owner (subject to bikeshedding) which instructs hyde to leverage git blame (or a comparable command for other version control systems) to make a best guess at the owner of a particular code segment (class, function, file, etc). This could be used to autofill the owner field of the emitted YAML and reduce the amount of manual work needed to update one's docs.
