Namespaced NumbersAndWords

[dblock]

There're quite a few things in the global namespace, who knows what they collide with :) Namespaced everything to NumbersAndWords.

Small note: there're a couple of places where namespace were declared as module Foo::Bar, which is actually different from

module Foo 
  module Bar
  end
end 

The first case requires the namespace to have already been declared elsewhere, which would break depending in which order the files are loaded.

Btw, you can view the diff with w=1 which turns off showing differences in spaces and tabs and makes it a lot easier on the eyes: https://github.com/kslazarev/number_to_words_ru/pull/7/files?w=1

Wow, I didn't know about w=1. Thank you.

You'll right in both cases. :)
But I don't understand your double empty line at the end of each file.

Also for single line ruby block we should use '{}' , as more preferable approach, I think. We must use code space more rational. (but code line length should not be greater 90)
