SeqQC templates: ability to get id_run, position, tag_index from any type of result object #500
Description
... coming from a file system, from a database with no id_run, position, tag_index columns, having one component or more...
Create a role defining get_X methods, where X is id_run, position, tag_index, subset, inherit from this role in both parent chack and result object.
