# Encapsulates the pattern of wanting to validate a password or email
# address field with a confirmation. For example:
#
# Model:
# class Person < ActiveRecord::Base
# validates_confirmation_of :user_name, :password
# validates_confirmation_of :email_address,
# :message => "should match confirmation"
# end
#
# View:
# <%= password_field "person", "password" %>
# <%= password_field "person", "password_confirmation" %>
#
# 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 accessors 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").
# * <tt>:on</tt> - Specifies when this validation is active. Runs in all
# validation contexts by default (+nil+), other options are <tt>:create</tt>
# and <tt>:update</tt>.
# * <tt>:if</tt> - Specifies a method, proc or string to call to determine
# if the validation should occur (e.g. <tt>:if => :allow_validation</tt>,
# or <tt>:if => Proc.new { |user| user.signup_step > 2 }</tt>). The
# method, proc or string should return or evaluate to a true or false
# value.
# * <tt>:unless</tt> - Specifies a method, proc or string to call to
# determine if the validation should not occur (e.g.
# <tt>:unless => :skip_validation</tt>, or
# <tt>:unless => Proc.new { |user| user.signup_step <= 2 }</tt>). The
# method, proc or string should return or evaluate to a true or false value.
# * <tt>:strict</tt> - Specifies whether validation should be strict.
# See <tt>ActiveModel::Validation#validates!</tt> for more information
