docs: Will return a DataFrame with coverage information (if available) for each repo in the project).
  
          If there is a .coverage file available, this will attempt to form a DataFrame with that information in it, which
          will contain the columns:
  
           * repository
           * filename
           * lines_covered
           * total_lines
           * coverage
  
          If it can't be found or parsed, an empty DataFrame of that form will be returned.
