C++ wrapping

I wouldn't really advocate using the C-style function-based or
iterative GSL routines with functions defined by classes in C++.  It
is too horrible, as demonstrated by the code flying past.

Regarding QT's method, as I'm sure everyone knows it uses MOC
preprocessor files to implement its object system, and these are a
non-standard hack.

For numerical code one needs to be able to write a single high-level
description of the algorithm, and then do code-generation to
specialise it.  This requires a powerful macro facility to enable
transformations before compilation, which is really only found in
Lisp.  I don't consider C++ templates to be adequate, they are also a
hack, and are not programmable in the same way as lisp macros.
