Usage
# Equivalent to Array#Sample but usable on
# ActiveRecord models and relations!
#
# Returns a result with two quick queries:
#
# > Spree::Product.sample
# (4.9ms) SELECT COUNT(*) FROM "spree_products"
# (3.8ms) SELECT "spree_products".* FROM
# "spree_products" LIMIT 1 OFFSET 4132
#
# => #<Spree::Product id: 414, name: "...
#
