      Description

      Add an interpreter that can evaluate logical RelNodes (such as FilterRel, TableAccessRel).

      The motivation is similar to OPTIQ-107 but this feature request would interpret logical RelNodes, not RelNodes that implement EnumerableRel. This case would eliminate planning time as well as the janino step.

      We should explicit sources, sinks and start/run/stop methods. A bit less efficient, but gives us the opportunity for detailed tracing and even single-stepping.

      Put code in a new package net.hydromatic.optiq.impl.interpreter.
