Sample functionality for Active Record.

Don't use this for large set of data for now (See #1).

User.count # => 0
User.sample => nil

User.count # => 100
User.sample => #<User id: 42, ...>
User.sample(2) => #<ActiveRecord::Relation [#<User id: 1>, #<User id: 42>]>

User.count # => 100
User.sample(200) => #<ActiveRecord::Relation [All Users but shuffled]>

Add this line to your application's Gemfile:

gem "active_sample"

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_sample
