Detailed Description

DataBlockPtr acts like a RefCountedBlockPtr that has two additional pieces of functionality:

1. it contains a pointer to a Smarts DataObject used for constructing and running the Smarts data-flow graph.
2. it can notify an observer when the destructor is called (i.e. when views of an engine go away).

DataBlockController is an extension of the RefBlockController used by RefCountedBlockPtr. This is where the data object and observable actually reside.
