Richard Newman 833ff92436 Simple aggregates. (#584) r=emily ... * Pre: use debugcli in VSCode. * Pre: wrap subqueries in parentheses in output SQL. * Pre: add ExistingColumn. This lets us make reference to columns by name, rather than only pointing to qualified aliases. * Pre: add Into for &str to TypedValue. * Pre: add Store.transact. * Pre: cleanup. * Parse and algebrize simple aggregates. (#312) * Follow-up: print aggregate columns more neatly in the CLI. * Useful ValueTypeSet helpers. * Allow for entity inequalities. * Add 'differ', which is a ref-specialized not-equals. * Add 'unpermute', a function for getting unique, distinct pairs from bindings. * Review comments. * Add 'the' pseudo-aggregation operator. This allows for a corresponding value to be returned when a query includes one 'min' or 'max' aggregate.		2018-03-12 15:18:50 -07:00
