[Bf-committers] How about adding boost uBLAS library to blender/extern?

The new IK algorithms developed at the KUL use the uBLAS template
library from boost for matrix definition and operation.
In order to minimize code change when porting to Blender, I am asking if
it would be acceptable to add that library in blender/extern.
It is a template library, so it will not increase the size of the
executable more than necessary. It allows high level abstraction and yet
it is almost as fast as an add-hoc C implementation because it uses the
advanced technique of template expressions. The drawback is that it
requires a modern C compiler: gcc 3.2.3 and above, MSVC 7.1 and above,
ICC 8.0 and above (older compiler are supported with an earlier version
of the library). I guess this is not a limiting factor?
In terms of number of files, I extracted a subset of boost that contains
all the necessary files to compile uBLAS: 10Mb in 1650 files.
The alternative is to implement add-hoc C functions or reuse the TNT
template library that is used by IK_Solver (intern/iksolver/intern/TNT).
This library is much smaller and provide similar functionality but it is
not as fast.
For the interested ones, I've started a wiki on the IK project:
