This version removes nalexander's lovely matrix code. It turned out that scalar and tuple bindings are sufficiently different from coll and rel -- they can directly apply as values in the query -- that there was no point in jumping through hoops to turn those single values into a matrix. Furthermore, I've standardized us on a Vec<TypedValue> representation for rectangular matrices, which should be much more efficient, but would have required rewriting that code. Finally, coll and rel are sufficiently different from each other -- coll doesn't require processing nested collections -- that my attempts to share code between them fell somewhat flat. I had lots of nice ideas about zipping together cycles and such, but ultimately I ended up with relatively straightforward, if a bit repetitive, code. The next commit will demonstrate the value of this work -- tests that exercised scalar and tuple grounding now collapse down to the simplest possible SQL. |

This sub-crate implements the core types used by the query parser, translator, and executor — variables, find specifications, etc.
The edn sub-crate implements some even lower-level types, such as Keyword.
