FeatureExamples

This example showcases and provides example usage of specific Atomic technology features. The examples are minimal and strive to use minimal API and concise code and many are ported from upstream Urho3D. The examples are also presented in the form of a "multi-example" so they can be easily built and tested. This also helps catch object lifetime issues, etc.
