conflict with NArray's NMatrix

[kojix2]

Hi @v0dro

Thank you for your great gem!
But daru conflict with Tanaka's NArray.

 Error:  /narray-0.6.1.1/nmatrix.rb:8:in `<top (required)>': uninitialized constant NArray (NameError)

daru.rb

lib_underscore = library.to_s.gsub(/-/, '\_').gsub('/', '\_')
create_has_library :'nmatrix/nmatrix'

daru/accessors/nmatrix_wrapper.rb

end if Daru.has_nmatrix_nmatrix?

This work. But not cool.

Hmm thanks for reporting this. I havnt quite updated the nmatrix dependency ever since nmatrix was newly updated.

We'll just need to change the require 'nmatrix' in daru to latest one that does not conflict with narray.

Could send a PR changing require 'nmatrix' to require 'nmatrix/nmatrix'?
