# Converts a collection of elements into a formatted string by calling
# <tt>to_s</tt> on all elements and joining them. Having this model:
#
# class Blog < ActiveRecord::Base
# def to_s
# title
# end
# end
#
# Blog.all.map(&:title) #=> ["First Post", "Second Post", "Third post"]
#
# <tt>to_formatted_s</tt> shows us:
#
# Blog.all.to_formatted_s # => "First PostSecond PostThird Post"
#
# Adding in the <tt>:db</tt> argument as the format yields a comma separated
# id list:
# Extends <tt>Array#to_s</tt> to convert a collection of elements into a
# comma separated id list if <tt>:db</tt> argument is given as the format.
#
# Blog.all.to_formatted_s(:db) # => "1,2,3"
