[Numpy-discussion] Moved matrix class into separate module

[David Cournapeau]

Hi,

I just wanted to mention I integrated a patch from some time ago to make
numpy.core independent from other numpy modules. This is really useful
when working on involved changes at the C level. This meant moving some
stuff around, in particular the matrix class and utilities is now into
numpy.matrixclass module. The numpy namespace is of course unchanged.

cheers,

David
