WIP: refactor so multiple graphs can be defined for a given slug WIP: fixed scale view but broke 'All Parent' graph WIP: working state. All views working properly WIP: Refactor graph_map into two collections; measure_level_graphs and scale_level_graphs WIP: refacter GroupedBarColumnPresenter to accept a 'construct' instead of specifying measure or scale WIP: fix scale graphs being shown on incorrect view WIP: Merge parents_by_language class with parents_by_language_by_scale so it can handle display of both measure-level and scale-level graphs
