The only non-default SMF was the copy-assignment operator, which was calling the assign() function. However, that call seems to be redundant, as the other object should have already called it during construction, and since the implementation uses QESDP, the copy-assignment should just increase the ref count. The tests that were added in the previous patch confirm that the call is not needed. This means that we can apply Rule Of Zero and remove all SMFs.
