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 basic coloring of CLI output.

Toggle it on or off with 'timer on' and 'timer off'.

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

2ac7a1b1de Add a feature flag to control the use of rusqlite's bundled SQLite. r=emily
You can use this in conjunction with setting SQLITE3_LIB_DIR to control which SQLite is used.

See https://github.com/jgallagher/rusqlite for more.

Also add recent contributors to the authors array.

66e6fef75e Define Store, use TabWriter in the CLI for aligning columnar output. (#540) r=emily

  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.

9740cafdbd Automatically remove trailing whitespace from text files. (#527) r=rnewman
This was done using the following shell script:

```
find . -type f -not -path "*target*" \
       '(' -name '*.rs' -o -name '*.md' -o -name '*.toml' ')' -print0 | \
    xargs -0 sed -i '' -E 's/[[:space:]]*$//'
```

Which is admittedly imperfect, but manages to hit everything that was a problem in this repo.

c95ec13ffe Begin moving web server to a separate crate. (#448) r=bgrins
This doesn't yet introduce a working Cargo.toml for 'mentatweb', but it
does allow RLS to build correctly without errors, and it reduces the
core library's dependency space, which is more important in the short
term.
