Yes, exactly, the interface is one of the main reason for me to team up
with C++ pears, to try and get that right. That a thing where feedback
is very helpful! As I see it, there are a couple of interface issue:
* containers for the multivariate parameters (vectors and matrices) and
operators on those containers -inverse of a matrix-
* specifying generic functions/properties of multivariate densities,
that would apply to *any* multivariate density
* the number of Gaussian identities/operators/function/algorithms to
include, there are many, some widely used, some obscure...

I'm trying to form a team -asking friends- and will probably be able to
get some knowledgeable C++ developers to contribute to this. As I
understand, the procedure is to get it working first & then submit it to
the sandbox? How would I be able to get boost developers involved during
the early interface design phase?
