Ok, moving on, done.

I'll try to have the traits supporting the Yale sparse (compressed) data
structure to be operational by then. A request for those bindings: can they
be made more like the other bindings? I.e., with a directory/include
structure, or something? Especially the UMFPACK bindings seems to be one big
file. In addition, is there a lot to do for the const-overloads of those?

Eigen should be able to do algorithms that require a linear array as data
structure. It also has a Sparse module including a container for it.

TNT... looks quite dead indeed. I don't mind having ~5 kB of bindings code
for it, though. I also won't mind if you feel like deleting it :-).
