# class Product
# include ::EacRailsUtils::Models::InequalityQueries
#
# add_inequality_queries(:foo)
# end
#
# This add the following scopes:
#
# Product.by_foo_gt(value) # Equivalent to Product.where("foo > ?", value)
# Product.by_foo_gteq(value) # Equivalent to Product.where("foo >= ?", value)
# Product.by_foo_lt(value) # Equivalent to Product.where("foo < ?", value)
# Product.by_foo_lteq(value) # Equivalent to Product.where("foo <= ?", value)
