PImplementation about core.matrix

[mikera]

The idea is to allow for generic matrix construction. See how it is implemented in vectorz-clj if you like:

In general, can you ask this kind of question on the Numerical Clojure discussion list rather than a GitHub issue? It's a better place for this kind of discussion.

Also be aware that we are still at experimental stage, so all of this is subject to change :-)
