// Helper classes for creating new style state objects out of an arbitrary set of subobjects.
// Uses STL
//
// Start by instantiating CD3DX12_STATE_OBJECT_DESC (see it's public methods).
// One of its methods is CreateSubobject(), which has a comment showing a couple of options for
// defining subobjects using the helper classes for each subobject (CD3DX12_DXIL_LIBRARY_SUBOBJECT 
// etc.). The subobject helpers each have methods specific to the subobject for configuring it's 
// contents.
