Concatenation plugin for Shrine

# The `concatenation` plugin allows you to assign to the attacher a
# cached file which is composed of multiple uploaded parts. The plugin
# will then call `#concat` on the storage, which is expected to
# concatenate the given parts into a single file. The assigned
# attachment will then be a complete cached file.

Response to regarding "ActiveRecord is Reinventing Sequel"

Hey Sean,

I just encountered your "The Bike Shed" podcast, concretely number #56 where you were talking about the "ActiveRecord is Reinventing Sequel" post I wrote. I'm sorry that this post struck you as negative, and that it made you feel like I was attacking you. I admit that I did feel some negative energy while I was writing it, but I still felt like I needed to say it.

Firstly, you said in the podcast that you would like to read an article which shows parts where Sequel is better than ActiveRecord. However, I did link my previous "Ode to Sequel" post in the first paragraph of my post, and soon after added two more. So I think it's a bit unfair that I was pr

View sequel.rb
require "sequel"
DB = Sequel.postgres("arel")
DB.create_table!(:movies) { primary_key :id }
class Movie < Sequel::Model
# Asterisk (I agree this one isn't ideal){count{}.*} # SELECT count(*) FROM "movies"
