Simplified UML Diagram

Here's a simplified UML diagram of the basic relationships from my
perspective.  I omitted some of the detail because it makes the
whole thing difficult to understand.  I do have the basic
relationships between component types, steps, step containers, and
pipelines.

I've attached the UML diagram and the violet source (see 
http://www.horstmann.com/violet/ for the tool).
