chiselCloneType is called at the top-level of a clone chain.
chiselCloneType is called at the top-level of a clone chain. It calls the client's cloneType() method to construct a basic copy of the object being cloned, then performs any fixups required to reconstruct the appropriate core state of the cloned object.
a copy of the object with appropriate core state.
cloneType must be defined for any Chisel object extending Data.
cloneType must be defined for any Chisel object extending Data. It is responsible for constructing a basic copy of the object being cloned. If cloneType needs to recursively clone elements of an object, it should call the cloneType methods on those elements.
