81af295948 Start installing SQL schema. (#171) r=rnewman
* Start installing the SQLite store and bootstrapping the datom store.

* Review comment: Decomplect V2_IDENTS.

* Review comment: Decomplect V2_PARTS.

* Review comment: Pre: Expose Clojure's merge on Value instances.

* Review comment: Decomplect V2_SYMBOLIC_SCHEMA.

* Review comment: Decomplect V1_STATEMENTS.

* Review comment: Prefer ? to try!.

* Review comment: Fix typos; format; add TODOs.

* Review comment: Assert that Mentat `Schema` is valid upon creation.

* 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.

2592506288 Implement parsing of simple :find expressions. (#196) r=nalexander
* Test the mentat_query directory on Travis.

* Export common types from edn.

This allows you to write

  use edn::{PlainSymbol,Keyword};

instead of

  use edn:🔣:{PlainSymbol,Keyword};

* Add an edn::Value::is_keyword predicate.

* Clean up query, preparing for query-parser.

* Make EDN keywords and symbols take Into<String> arguments.

* Implement parsing of simple :find lists.

* Rustfmt query-parser. Split find and query.

* Review comment: values_to_variables now returns a NotAVariableError on failure.

* Review comment: rename gimme to to_parsed_value.

* Review comment: add comments.

c4735119c4 Implement a basic EDN parser. (#149) r=rnewman,bgrins,nalexander
The parser mostly works and has a decent test suite. It parses all the
queries issued by the Tofino UAS, with some caveats. Known flaws:

* No support for tagged elements, comments, discarded elements or "'".
* Incomplete support for escaped characters in strings and the range of
  characters that are allowed in keywords and symbols.
* Possible whitespace handling problems.
