// HOWTO:
//
// unary_func, binary_func, ternary_func - base classes wrapping OpenCL functions that
// you want to test.
// 
// To create a wrapper class for given function, you need to create a class derived from correct
// base class (unary_func, binary_func, ternary_func), and define:
//
// * std::string str() method which should return class name in OpenCL ("abs", "abs_diff"),
// * operator(x), operator(x, y) or operator(x,y,z) depending on arity of the function you wish
// to test, method should work exactly as the tested function works in OpenCL
// * if it's needed you can overload min1, max1, min2, max2, min3, max3 methods with returns min 
// and max values that can be generated for given input (function argument) [required for vec 
// arguments],
// * if you want to use vector arguments (for example: cl_int2, cl_ulong16), you should look at
// how int_func_clamp<> is implemented in integer_funcs/numeric_funcs.hpp.
//
// To see how you should use class you've just created see AUTO_TEST_CASE(test_int_numeric_funcs)
// in integer_funcs/numeric_funcs.hpp.
