# This DeprecatedInstanceVariableProxy transforms instance variable to
# deprecated instance variable.
#
# It differs from ActiveSupport::DeprecatedInstanceVariableProxy since
# it allows to define a custom message.
#
# class Example
# def initialize(deprecator)
# @request = Spree::DeprecatedInstanceVariableProxy.new(self, :request, :@request, deprecator, "Please, do not use this thing.")
# @_request = :a_request
# end
#
# def request
# @_request
# end
#
# def old_request
# @request
# end
# end
#
# When someone execute any method on @request variable this will trigger
# +warn+ method on +deprecator_instance+ and will fetch <tt>@_request</tt>
# variable via +request+ method and execute the same method on non-proxy
# instance variable.
#
# Default deprecator is <tt>Spree::Deprecation</tt>.
