There are two tasks:

1. Use a Factory to create tables that represent a materialized view.
2. Add an entry to the schema only if a materialized table was created in defineMaterialization.

I'll open a WIP progress soon.

1. was easy to implement.
2. is proving to be hard because rest of the code requires a CalciteSchema.TableEntry object which is available only when a table is added to schema. I dont know how to get an object for an existing entry.
