how to get the class handle from python class about ffpython

[fanchy]

now ffpython has supported that case, i have update the ffpython.h and example.cpp, you can see the example.cpp how to call pyclass method. By the way, ffpython now can call python lamda function.
But you should pay more attention when using that api, because you should call Py_DECREF when you don't need the reference of the python handle.
example python code:

class pyclass_t:
    def __init__(self):
        print('pyclass_t init....')
    def sayHi(self, a1, a2):
        print('sayHi..', a1, a2)
def test_cpp_obj_return_py_obj():
    return pyclass_t()
def test_cpp_obj_return_py_lambda():
    def test_lambda(a1):
        print('test_lambda....', a1)
    return test_lambda

example c++ code:

void test_py_class_lambda(ffpython_t& ffpython)
{
    PyObject* pobj = ffpython.call<PyObject*>("fftest", "test_cpp_obj_return_py_obj");
    ffpython.obj_call<void>(pobj, "sayHi", 1, string("soNice"));

    PyObject* pFunc= ffpython.call<PyObject*>("fftest", "test_cpp_obj_return_py_lambda");
    ffpython.call_lambda<void>(pFunc, 112233);

    Py_DECREF(pFunc);
    Py_DECREF(pobj);

}
