Detailed Description

This file implements covariant returns via smart pointers for a polymorphic clone function. The implementation largely follows the solution presented by the FluentC++ blog. Some class/tag names have been updated to be clearer, in my opinion. Additionally, a semi-useful predicate has been added to aid metaprogramming down the line.
