#docs_for(code_object) ⇒ Object

Return docs for the code_object, adjusting for whether the code_object has yard docs available, in which case it returns those. (note we only have to check yard docs for modules since they can have multiple docs, but methods can only be doc’d once so we dont need to check them)
