Baseline Heterogeneous Example (#1460)

* Baseline Heterogeneous Example

This PR introduces a baseline heterogeneous example, including both a
Slang file and an associated C++ helper file.  This refactoring
primarily moves the Slang file "into the driver's seat" while
maintaining that the C++ side still does most of the actual work.

* Fix to prelude path
