Follow up of this [conversation|https://mail-archives.apache.org/mod_mbox/incubator-calcite-dev/201503.mbox/%3CCANG6QPx7eLmUrkXRTY09yGw7GchMNRSSDnRCQEnd_3z%3DJCX%3Dgg%40mail.gmail.com%3E]

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.
