List datasets

List the datasets a report can read, or one product's (product: discovery, experience or research). Each names its id, label and description, whether it aggregates (rows and columns grouped by its dimensions, each cell its measures) or lists records (one row per interaction, its dimensions as fields), how it reads time (window: the trailing 30-day results window ending on the as-of day a date range chooses; range: the range itself), its dimensions and measures, how many row and column dimensions a report may group by, whether it compares with the window 30 days earlier, the records dataset a cell opens (drill), and what a new report of it opens on.
