// Overview:
// Test multiple inheritance with and without virtual bases. 
// API Information:
// N/A
// Details:
// - Test multiple inheritance with virtual bases. Using a virtual
// base class, copy one or more strings from the "producer" object 
// to the "consumer" object. Verify that results are as expected.
// - Test multiple inheritance without virtual bases. Using a non-
// virtual base class, copy one or more strings from the "producer" 
// object to the "consumer" object. Verify that results are as expected.
// Platforms/Drives/Compatibility:
// All.
// Assumptions/Requirement/Pre-requisites:
