* Part 1 - Create as_edn_value function.
* Do not include defaults inside output.
* Pretty-printed by default. Do we want to make that a flag?
* Includes simple test just to make sure it works.
* Part 2 - only include ident if available.
* Part 3 - Remove spacing and newlines as unnecessary.
* Update function to build edn::Value directly rather than parsing from string
* Update test to actually test the functionality.
* Address review comments ncalexan.
* Rename `as_edn_value` to `to_edn_value`.
* Move `db/src/values.rs` to `core/src/values.rs` so we can reference inside `core/src/ib.rs`.
* Add `lazy-static` crate to core `Cargo.toml`
* Expose `values` as a public module from `core`.
* Update references to values in `db/src/bootstrap.rs` & `db/src/lib.rs`.
* Add new static vars for `DB_FULLTEXT`, `DB_INDEX` & `DB_IS_COMPONENT`.
* Use static vars exposed in `values` inside `to_edn_value`.
* Remove `db/id` as key in attribute output and use `entid` as `db/ident` if no `ident` is found for that `entid`.
* Update test to match new expected output.
* Add doc comment for function
* Address review comments ncalexan.
* Update function docstring to give clearer description of function.
* Do not all entid at all to output.
* Clean up code fetching ident (make it rustier).
* Address review comments rnewman.
* Extract out to new `to_edn_value` functions code for creating `edn::Value`\'s for `ValueType` and `Attribute`.
* Use `map()` to create schema edn value rather than a loop.
* Address review comments rnewman.
* pass cloned instance of ident to `Attribute::get_edn_value`.
* update `use` import for `edn`.
* remove unnecessary call when using ident as key on `associate_ident`.
* Fixed bug whereby we didn't differentiate between `db.index/value` and `db.index/identity` when generating `edn::Value`
* Add extra assert at the end to ensure we get the same output when we convert the same schema to edn multiple times
* Move check for type of uniqueness to `match` statement.
* Also use `iter` instead of `into_iter` when iterating schema map.
* Start installing the SQLite store and bootstrapping the datom store.

* Review comment: Improve conversion to and from SQL values.
This patch factors the fundamental SQL conversion maps
between (rusqlite::Value, value_type_tag) and (edn::Value, ValueType)
through a new Mentat TypedValue. (A future patch might rename this
fundamental type mentat::Value.)
To make certain conversion functions infallible, I removed
placeholders for :db.type/{instant,uuid,uri}. (We could panic
instead, but there's no need to do that right now.)
* Review comment: Always uses bundled SQLite in rusqlite.
This avoids (runtime) failures in Travis CI due to old SQLite
versions. See 432966ac77.
* Review comment: Move semantics in `from_sql_value_pair`.
* Review comment: DB_EXCISE_BEFORE_T instead of ...BEFORET (no underscore).
* Review comment: Move overview notes to the Wiki.
