Minimal set of expressions and operators for defining predicates over vortex arrays. This does **_not_** express recursive expression trees, but instead restricts the algebra to disjunction-of-conjunction (OR-of-AND) of field/value comparison operations. I tried to restrict this to a manageable set of expressions that we will definitely need as to avoid bloat; the expectation here is that this may grow over time. Subsequent changes will introduce: - [ ] A pushdown API for vortex arrays - [ ] Array pushdown implementations for the various expressions Supercedes #308

Minimal set of expressions and operators for defining expressions over vortex arrays. Takes inspiration from datafusion but is restricted to filter predicates and rewritten to use the vortex type system.
