Change #dv to #to_dv?

[lokeshh]

Array or ranges can be initialized to Daru::Vector with dv method like

[15] pry(main)> (1..3).dv
=> 
#<Daru::Vector:22990900 @name = nil @metadata = {} @size = 3 >
    nil
  0   1
  1   2
  2   3

I think to_dv is better because its intuitive and easy to remember similar to to_i, to_a, etc.

+1 to this proposition.
Also, I'm not sure it is a good practice to pollute Ruby objects with such a short names.
I'd prefer having Array#to_daru_vector by default, and to_dv shortcut defined in something like daru/shortcuts (not required by default).

Ok works. to_daru_vector is better and more suited for a Ruby class change.

Also I like the daru/shortcuts idea.
