Updated cv2.cpp to support Python 3 API. Added a header with defines to enable the module to compile with either python 2 or 3 without changes. 12 years ago			`/*M///////////////////////////////////////////////////////////////////////////////////////`

Support PyString_AsString() in Python 3 < 3.3 In Python 3, version 3.3+, PyUnicode_AsUTF8() provides similar functionality to Python 2's PyString_AsString(). In older versions of Python 3, there is no public function to provide the same functionality. However, the "internal" _PyUnicode_AsString() does provide that functionality, so use it to replace PyString_AsString(). With this patch, cv2 should compile for Python 3.[0-2]. 11 years ago
