* 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. |

This crate turns an algebrized Datalog query into a domain-specific representation of a SQL query, and then uses mentat_sql to turn that into a SQL string to be executed.
This subsumes both planning and query construction, because in Mentat the SQL query is effectively a query plan.
