C++ Bindings Completeness

[strangeup]

I noticed that the c++ bindings appear to be unfinished, am I right in this assumption? There doesn't appear to be any support for the symmetric routines (though it seems straightforward for me to work around that) which drew my attention to this. The main question is, would this code be usable without much work as an interface with arpack?

So far my attempts manage to compile but result in obviously dubious eigenvalues. I can't see anything superficially wrong with my code, however, so I was wondering if I was missing something a bit more subtle that hadn't yet been implemented.
