# This allows generation of "codes"... namely for part-numbers and unique identifiers for records
# It's especially effective with FactoryGirl's sequences.
#
# Examples:
#   Factory.define :whatever do |whatever|
#     whatever.sequence(:unique_code) {|n| generate_code(n, :length => 4, :numeric => true) }
#     # ...
#   end
