Description

In discussions for CALCITE-296, pipfiddle suggested that we move the enumerable adapter – that implements the core relational expressions by generating iterator-like code – out of core.

In that change, we changed package names. In this change, we keep the same package names, but move files into a new directory structure, and maven module, enumerable. Considerable refactoring is required. A lot of tests will have to be moved, because there is no implementation (except the interpreter). Other adapters (e.g. mongo) will continue to depend on this adapter, at least until they can be changed to use a non-code-generation interfaces, like ScannableTable and Interpreter.

Goal is to fix before 1.0.
