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.

1817ce7c0b Performance and cleanup. r=emily
* Use fixed-size arrays for bootstrap datoms, not vecs.
* Wide-ranging cleanup.

    This commit:
    - Deletes some dead code.
    - Marks some functions only used by tests as cfg(test).
    - Adds pub(crate) to a bunch of functions.
    - Cleans up a few other nits.

f42ae35b70 Update cache on write. (#566) r=emily
* Use the cache to make constant queries super fast.
* Fix translate tests to match: we no longer generate SQL for many of them!
* Accumulate additions and removals into the cache.
    * Make attribute cache clone-on-write; store it in Metadata.
    * Allow caching of fulltext attributes, interning strings.

Speed up EDN parser (fixes #445) (#581) r=nalexander
Fixes from @kevinmehall.

* Prefer character sets over backtracking in the EDN parser.
* Avoid duplicate effort when parsing floats in the EDN parser.
* Clean up duplicate position tracking code.

This turns out to have little performance impact, but makes the grammar
much cleaner.

* Fix EDN work to pass tests with correct numeric precedence.

e33fe71c47 Rework caching and use it inside the query engine. (#553) r=emily
This puts caching in mentat_db, adds a reverse lookup capability for
unique attributes, and populates bidirectional caches with a single
SQL cursor walk.

Differentiate between begin_read and begin_uncached_read.

Note that we still allow toggling within InProgress, because there might be
transient local state that makes starting a new transaction impossible.

Add EntityBuilder.add_kw. (#558) r=emily
* Add EntityBuilder.add_kw.

This allows you to skip your own attribute lookups, at the cost of
potentially doing the work more than once.

Also does value type checking.

Timing and colorizing in the CLI. (#552) r=grisha
* Add basic coloring of CLI output.
* Add a timer to the CLI.

Toggle it on or off with 'timer on' and 'timer off'.
Output is colorized.

* Add VSCode configuration files.

These allow you to build and run the CLI, build Mentat, or run all tests.

Create generalized in-memory cache for attributes (#525)
* Nit: Alphabetical ordering of imports

* Create Cache and provide functions for calling it

* Get tests working. Move to using NamespacedKeyword over KnownEntid in function signature

* Add is_cached check to caching tests

* Move lazy and add/remove boolean flags to enums

* Move function definitions into generic trait and implement trait for AttributeCache

* Remove lazy cache and generalize cache

* Update tests

* Eager cache becomes simple key value store. AttributeMap handles attribute storing specifics

* Update tests to test presence of correct values in cache

* Move EagerCache, AttributeValueProvider and ValueProvider into mentat_db

* Add test for get_for_entid

* Add test for lookup attribute

* Make caches cloneable. Add value_for alongside values_for

* Use cache in attribute lookups

* Split test for values and value and add cardinality

* address review feedback r=rnewman

66e6fef75e Define Store, use TabWriter in the CLI for aligning columnar output. (#540) r=emily
* Define Store, which is a simple container for a SQLite connection and a Conn.
  This is a breaking change.
* Return the FindSpec as part of QueryOutput, not just results.
* Switch to using stderr in appropriate places in CLI.
* Print columns in CLI output.

2614f498be Ergonomics improvements, including a kw macro. (#537) r=emily
* Add TypedValue::instant(micros).
* Add From<f64> for TypedValue.
* Add lookup_values_for_attribute to Conn.
* Add q_explain to Queryable.
* Expose an iterator over FindSpec's columns.
* Export edn from mentat crate. Export QueryExecutionResult.
* Implement Display for Variable and Element.
* Introduce a `kw` macro.

    This allows you to write:

    ```rust
    kw!(:foo/bar)
    ```

    instead of

    ```rust
    NamespacedKeyword::new("foo", "bar")
    ```

    … and it's more efficient, too.

Add `mentat::open`, eliminate use of `mentat_db` in some places.

3bf7459315 Allow customers to assert facts about the current transaction. (#225) r=rnewman
Also move `now` into core, implement microsecond truncation.

This is so we don't return a more granular -- and thus subtly different --
timestamp in a `TxReport` than we put into the store.
