Basic Unreal C++ gameplay framework plugins

These plugins were made when my C++ wasn't strong. They should only be used as "concepts" for your systems.

This collection contains:

• Huân helper: helper library for my development in Unreal.
• Currency system: a C++ thread safe currency system.
• Leveling system (requires currency system): a C++ multi-threaded leveling system sample.
• Rating system: a C++ multi-threaded rating system sample.

They have readme files and commented in the codes.
