# A Mock can fake an object.
#
# This is useful when frontend developers want to fill a page with
# mock data. Mocks can pre-define interface for real data.
#
# == Usage
#
# app/mocks/user_mock.rb:
#
# class UserMock < Neo::Rails::Mock
# def age
# mock.tagged?(:old) ? 78 : 23
# end
#
# def name
# "Uncle bob"
# end
#
# def logged_in?
# true
# end
#
# def sexy?
# mock.tagged?(:sexy)
# end
#
# def car
# mock.option(:car)
# end
# end
#
# Further...
#
# old_man = UserMock.new(:old)
# old_man.age # => 78
# old_man.name # => "Uncle Bob"
# old_man.car # => nil
#
# old_sexbomb = UserMock.new(:old, :sexy, :car => CarMock.new(:porsche))
# old_sexbomb.age # => 78
# old_sexbomb.sexy? # => true
# old_sexbomb.car # => CarMock
#
