C++ bindings for OpenCL Host API.
The interface is contained with a single C++ header file cl2.hpp and all definitions are contained within the namespace cl. There is no additional requirement to include cl.h and to use either the C++ or original C bindings; it is enough to simply include cl2.hpp.
The bindings themselves are lightweight and correspond closely to the underlying C API. Using the C++ bindings introduces no additional execution overhead.
