Add difference method to Array
I introduce a `difference` method equivalent to the `-` operator, but which accept more than array as argument. This improved readability, and it is also coherent with the `+` operator, which has a similar `concat` method. The method doesn't modify the original object and return a new object instead. I plan to introduce a `difference!` method as well. Tests and documentation are included. It solves partially https://bugs.ruby-lang.org/issues/14097 From: Ana María Martínez Gómez <firstname.lastname@example.org> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64921 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
