  1. DDLInterpreter and Schema support streams, skeleton for SQLNamer 

    * The fact that whether a Table (in a particular Schema) is a stream or not is specified using the StreamingTable contraint.
* DDLInterpreter can convert a CreateStream node of a SQL AST into Schema. There are still some features missing though.
* The skeleton for SQLNamer and the corresponding test file added.
