PySide Shiboken Sequence Protocol

Support for the sequence protocol is achieved adding functions with special names, this is done using the add-function tag.

The special function names are:

Function name	Parameters	Return type	CPython equivalent
__len__	PyObject* self	Py_ssize_t	PySequence_Size
__getitem__	PyObject* self, Py_ssize_t _i	PyObject*	PySequence_GetItem
__setitem__	PyObject* self, Py_ssize_t _i, PyObject* _value	int	PySequence_SetItem
__contains__	PyObject* self, PyObject* _value	int	PySequence_Contains
__concat__	PyObject* self, PyObject* _other	PyObject*	PySequence_Concat

You just need to inform the function name to the add-function tag, without any parameter or return type information, when you do it, Shiboken will create a C function with parameters and return type definied by the table above.

The function needs to follow the same semantics of the CPython equivalent function, the only way to do it is using the inject-code tag.
