/**
 * @brief A templated class to allow one to wrap a CPU operator as a CUDA
 * operator.
 *
 * This class can be used when one does not have the CUDA implementation ready
 * yet for an operator. Essentially, what this op does is to automatically
 * deal with data copy for you. Plausibly, this causes a lot of overhead and
 * is not optimal, so you should use this operator mostly for quick prototyping
 * purpose.
 *
 * All the input and output of the original operator should be TensorCPU.
 *
 * Example usage: if you have a class MyMagicOp that is CPU based, and you use
 * the registration code
 *     REGISTER_CPU_OPERATOR(MyMagic, MyMagicOp);
 * to register the CPU side, you can create its corresponding GPU operator
 * (with performance hits of course) via
 *     REGISTER_CUDA_OPERATOR(MyMagic,
 *                            GPUFallbackOp);
 * Note that you will need to make sure that the operators actually share the
 * same name.
 *
 * Advanced usage: if you want to have some specific outputs never copied, you
 * can use the SkipOutputCopy template argument to do that. For example, if
 * MyMagic produces two outputs and the first output is always going to live on
 * the CPU, you can do
 *     REGISTER_CUDA_OPERATOR(MyMagic,
 *                            GPUFallbackOpEx<SkipIndices<0>>);
