Python bindings

pythonBuffer.h defines an automatic reflection of types and objects to Python (Python3 stable API targeted). To use this, include this header file, and then use the following macros to define objects, functions and types in the Python module being created:

CLASSDESC_ADD_GLOBAL(object)

adds a global object object to the module. It should be without any namespace qualifications, as Python cannot copy with colons in identifier names, but the macro can be used within any namespace.

CLASSDESC_ADD_FUNCTION(function)

Same as with object, but adds a static function to the module.

CLASSDESC_DECLARE_TYPE(type,...)

Declares a type, which can be created using Python constructors - ie x=MyType(), where MyType is the name of a C++ type with a default constructor. Note if you need to pass parameters at construction time, then you can specify optional argument types: CLASSDESC_DECLARE_TYPE(IntType,int), which gets called form Python as x=IntType(0).

Once all objects are declared with these macros, finish off with CLASSDESC_PYTHON_MODULE(name), where name is the name of the module, which should match the name of the dynamic library.

NB for Windows users, you may need to compile and link pythonCAPI.cc, which provides stub routines for the Python C API to satisfy the linker.

An example of all this workign can be found in the RESTProcessExample directory.
