> Implement SQL parser that can take a Vec<SQLToken> and produce a SQL AST.
> We can potentially break this down into separate JIRAs.
> It needs to support:
> * Single table SELECT ... FROM
> * WHERE
> * GROUP BY
> * ORDER BY
> * LIMIT
> It needs to support the following expressions:
> * Literals (long, string, double)
> * Identifiers
> * Binary expressions
> ** Arithmetic (+, -, *, /, %)
> ** Boolean (AND, OR)
> ** Comparison (=, !=, <, <=, >, >=, <>)
> * Unary boolean expression: NOT
> * CAST(expr AS type)
> * Aliased expressions: expr AS alias
> * Scalar functions
> * Aggregate functions
