* A helper class for loading and accessing json models.

* Creating a PartialModel will make the associated modelLocation automatically load.
* As such, PartialModels must be initialized at or before {@link ModelRegistryEvent}.
* PartialModels must be initialized during {@link net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent FMLClientSetupEvent}.
