Kernel Implementation APIs

The custom kernel-function implementation mainly depends on two parts: 1.APIs released by PaddlePaddle, including the context API, the tensor API, and the exception API; 2. APIs of the device encapsulation library. And the C++ API of PaddlePaddle has been released by the header file.

Note:There are abundant C++ API of PaddlePaddle. Three APIs will be introduced here and related classes and documents listed in corresponding websites are provided for developers.
