Fix conflict with NArray's NMatrix about nmatrix

[atimin]

I see only two ways. It is either to rename nmatrix.rb or to beg for narray's author to rename him file nmatrix.rb or to move it to narray/nmatrix.rb =(

Hey, I was looking through the NArray repository and it's more or less active. Shouldn't we try to talk to the author and somehow get to work together? I mean, having two teams building almost the same thing (I might be wrong!) sounds unnecessary.

What do you guys think?

Also, if the problem of this issue doesn't concern us anymore (because we're working on ruby-gsl), it should be closed. Either way, I think we should discuss what I said with NArray's author.

How's the rb-gsl fork going? If it's working, it should be sent upstream.

@masaomi Are you still doing any work on this?

Do you or @agarie want to prepare a patch for rb-gsl (to merge our fork back into the main)?

To use NArray with NMatrix, use the narray-nmatrix gem: http://github.com/SciRuby/narray
