Write an ANSI SQL DDL based Engine

Feedback from 10/2 meeting:

• Loading of a DDL should be its own operation.
• How that plugs into an engine (SCXML or otherwise) is a separate problem.
• How metadata (semantic info about columns) is added is an additional problem.

We should figure out how we would like to attack this from a usability perspective.

Some possibilities that were discussed:

• If using the SCXML engine, the DDL could be loaded via a Custom Tag, like the CSV assign custom tag in the current SCXML engine.
• We could write a new engine which takes a DDL file and some metadata in a non-graphical format, and generates datasets based off of that. As a new Engine, it would need to solve problems like data representation and working over distributors, etc.
