This method is called by the _RecursiveParsingPlan when created.
        Implementing classes should return a dictionary containing a ParsingPlan for each child they plan to parse
        using this framework. Note that for the files that will be parsed using a parsing library it is not necessary to
        return a ParsingPlan.

        In other words, implementing classes should return here everything they need for their implementation of
        _parse_multifile to succeed. Indeed during parsing execution, the framework will call their _parse_multifile
        method with that same dictionary as an argument (argument name is 'parsing_plan_for_children', see _BaseParser).
