glTFSample for Cauldron

glTFSample demonstrates how to use most of Cauldron’s features. It is also a useful reference for getting started with developing your own samples and prototypes.

Many GPUOpen samples were built using glTFSample code as a reference so getting familiar with it will help understand more advanced samples.
