# The person has to already have a password attribute (a column in the people table), but the password_confirmation is virtual.
# It exists only as an in-memory variable for validating the password. This check is performed only if password_confirmation
# is not nil and by default on save.
# The added +password_confirmation+ attribute is virtual; it exists only as an in-memory attribute for validating the password.
# To achieve this, the validation adds acccessors to the model for the confirmation attribute. NOTE: This check is performed
# only if +password_confirmation+ is not nil, and by default only on save. To require confirmation, make sure to add a presence
# check for the confirmation attribute:
#
# validates_presence_of :password_confirmation, :if => :password_changed?
#
# Configuration options:
# * <tt>message</tt> - A custom error message (default is: "doesn't match confirmation")
