Baking models [1.14.4+]

The conversion from block model json files into BakedModels occurs in several steps.

The two major stages are:

• UnbakedModels are created from the model files, storing information about the shapes in the model.  The vanilla examples of interest are: BlockModel (simple), VariantList (model chosen by blockstate), Multipart (model chosen by selectors)
• BakedModels are created from the Unbaked models, converting the shape information into a collection of Quads to be rendered.  For block and item models, the individual texture files in the UnbakedModels are also stitched together into a single texture sheet, and the appropriate texture coordinates for each quad are automatically updated to match.
