What's the entry point for Shape/DynamicObject?

[Timothy Baldridge]

I've been looking into the code behind Shape, DynamicObject, Layouts, etc.
And I can't seem to find what the top level object is. What should I be
calling to build a shape implementation? Should I be using
object.basic.ShapeBasic or something else? Also is there an example
language I could look at that uses these classes?

Thanks,

Timothy
